Fast and Sustainable Determination of Persistent Organic Pollutants from Organic Fertilizer Using Optimized Microwave-Assisted Extraction Method and Gas Chromatography-Mass Spectrometry
A microwave-assisted extraction was optimized for the evaluation of
persistent organic pollutants in liquid fertilizer samples. The extraction
process was defined by a 23 factorial design. The parameters (temperature
and sample and solvent volume) were optimized through the response surface
methodology (RSM). The data for the study were based on injection of a mix of
organochlorine pesticides. In optimized conditions, the microwave-assisted
extraction was carried out at 70℃ for 10 minutes using 10 mL of sample and 10
mL of solvent. This study was accomplishment to evaluate the statistical
influence of parameters: temperature, solvent volume and sample volume in the
microwave-assisted extraction of organochlorine contaminants present in
biofertilizer samples obtained from liquid humus and consequently to define the
best conditions of process.
