Enhanced Removal of Pb(II), Cd(II), and Zn(II) Ions from Aqueous Solutions Using EDTA-Synthesized Activated Carbon Derived from Sawdust

Onyedikachi G. Okpara, Osareme M. Ogbeide, Jeremiah N. Nworu, Jude I. Chukwuekeh, Solomon A. Igoche, Friday S. Alichi, Okechukwu E. Orinya
EDTA synthesized activated carbon derived from sawdust, was utilized as adsorbent for the removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The adsorptive characteristics and elemental composition of this activated carbon were studied using SEM and EDX techniques respectively, the analysis revealed that SAC-EDTA contained 71.95% by weight of carbon contents which are requisites for the high adsorption capacity. The effect of initial metals ions concentration, adsorbent dose, cont...

Effect of Lignocellulose Waste-Biomass Pretreatment of the Peels of Musa acuminata (Banana) and Ananas comosus (Pineapple) on the Production of Bioethanol via Solid-State Fermentation

Nyinchuo Evate, Pride Ndasi Ngwasiri, Wilson Agwanande Ambindei, Ngwa Martin Ngwabie, Martin Benoit Ngassoum
The use of fruits both domestically and industrially generates waste from their discarded peels which may lead to environmental pollution and contamination. This work aims at evaluating the effects of chemical pre-treatment of biomass on the physicochemical properties and the effects of process parameters on the production of ethanol via solid-state fermentation. The biomass was dried, ground and subjected to chemical pretreatment using H2SO4 and NaOH. pH, total Titratable ...

Ultraviolet Light (UV)-Induced Photocatalytic Degradation of Diclofenac Using Naturally Derived TiO2@rGO Composite

Lorenz E. Borromeo, Lea P. Bongat, John Patrick S. Nunez, Kirby F. Mendioro, Jocelyn R. Balisnomo
Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Assessment of Physiochemical Properties and Heavy Metals Concentration of Municipal Solid Compost (MSWC): A Case Study in Sokoto Metropolis, Nigeria

Muhammad Salisu Adamu, Imrana Bello, Buhari Idris, Malami Usman Muhammad, Bashar Abdullahi Hadi
Nowadays, farmers use municipal solid waste compost (MSWC) as fertilizer on their farmlands. Very scarce information on the quality of MSWC compost is available. As a result, the physiochemical characteristics of compost from ten (10) different dump sites in Sokoto City were evaluated in this study, and the results were compared with standards. According to the findings, the compost has a pH value ranging from 6.78 to 7.47, an electric conductivity between 2.16 to 6.48, organic carbon between (1...

Recovery of High-Added Value Materials from Vinasse Using Laser-Based Combustion

Hassan Nabeel Hassan Mustafa, Ahmed Mansor Taha Alzain, Mohammed U. Orsod, Ali A. S. Marouf
Vinasseisa liquid is produced during the process of fermentation and distillation of molasses for the production of ethanol. This paper studies the conversion of vinasse into valuable materials using laser, and the characterization of the provided products. For this purpose, vinasse sample was dried and combusted for 30 seconds using Nd: YAG laser with wavelength 1064 nm at output power 60 W continuous mode. The product of this process was characterized by an X-ray diffractometer (XRD), Fourier ...

Study on Radiation Dose Monitoring Based on Thermoluminescence Measurement Technology

Baolin Song, Jie Xu, Jiangxia Wan
The development of nuclear science and technology has greatly promoted the development of medical, agricultural, industrial and other industries. However, it is inevitable that more and more radiation safety problems are also accompanied. Accurate measurement of nuclear radiation dose is beneficial to the development of radiation safety. In this paper, based on the Optically Stimulated Luminescence (OSL) technology, the medium and coarse quartz tablets of 38 - 63 μm and 74 - 150 μm were prepared...

Physicochemical Analysis and Fatty Acid Content of Chemical and Traditional Extracts of Shea Kernel (Vitellaria paradoxa) from Kwara State Nigeria

Nnenna Eberechi Ofoegbu-Chibuzo, Uche John Chukwu, Ifedi Peter Okoye
Physicochemical analysis and fatty acid content of chemical and traditional extracted shea kernel (Vitellaria paradoxa) from Kwara State Nigeria have been studied. The extraction of shea butter from shea kernel using chemical and traditional techniques as well as its physicochemical analysis reveals that both the chemical extracted shea butter (CSB) and the traditional extracted shea butter (TSB) are very similar in properties save for the odor (slightly choking nutty odor for CSB and sli...

Current Trends in the Use of Cannabis sativa: Beyond Recreational and Medicinal Applications

Micah O. Omare, Joshua K. Kibet, Jackson K. Cherutoi, Fredick O. Kengara
Cannabis sativa finds application in the medical field as an opioid (medical marijuana) and as a recreational drug despite the fact that it is a prohibited drug substance in many countries. Currently, there are reports on the increasing trends in the number of deaths associated with the use of marijuana. Regardless of these dangers, some countries across the world have legalized the sale and use of marijuana for recreational and medicinal purposes. For these reasons, this review seeks to ...

Aviation Noise and Air Pollution: Results of a Study at Entebbe International Airport, Uganda

Austine Omolo, Christopher Angiro, Waganesh Admase Wagaye, Elly Olomo, Jasper Okino, Timothy Omara
For a landlocked country like Uganda, air transport is centermost to its import-export trade. As such, the aviation industry is important for its economic and political survival since it guarantees access to the outside world. This study reports on the noise and air pollution levels at Entebbe International Airport, Uganda. We found that the airport experiences irregular noise frequencies with the midday having the highest noise intensities that exceed permissible limits of 60 decibels. Carbon d...

Contemporary Trends in the Use of Khat for Recreational Purposes and Its Possible Health Implications

Micah O. Omare, Joshua K. Kibet, Jackson K. Cherutoi, Fredick O. Kengara
Khat is an ancient class C drug substance that is usually consumed for its stimulating effects induced by the intake of psychoactive alkaloids—cathinone and cathine which have been identified as precursors for oral cancer and impotence in men in addition to other health complications. Although khat is legal in Kenya, some countries have outlawed the cultivation, sale and possession of khat as a countermeasure against narcotic and psychotropic substances. The increasing trends in the use of khat ...
