Study on preparation and adsorption characteristics of multi-element modified iron-oxide-coated sand
改性铁覆膜砂的制备及吸附性能研究

The preparation of multi-element modified iron-oxide-coated sand(IOCS) by adding diatomite,bentonite,fly ash or active carbon was investigated.The effect of added adsorbent on adsorption capacity of various modified IOCS and the adsorption characteristics and mechanism were discussed respectively.The effects of diatomite,bentonite,activated carbon and fly ash on improvements of adsorption capacity of the multi-element modified IOCS are different.The adsorption capacity of multi-element modified IOCS depends...
