Abstract
[Objective]The aim was to study the new midified absorbent of cross-linking green alga with glutaraldehyde for adsorbing Cr6+.[ Method] The effects of glutaraldehyde mass fraction,green alga dosage,initial pH and temperature on cross-linking modifying and the effects of initial Cr6+ concentration,initial PH and modified green alga dosage on adsorbing Cr6+ were analysed. [ Result]The results showed that when the glutaraldehyde mass fraction was 5％ , green alga dosage was 0.4 g, initial pH was -0.5 and temperature was 40 ℃ ,the adsorption capacity of modified green alga was maximum for 40 mg/L Cr6 + solution. [ Conlusion ] The effects for influencing factors of adsorbing Cr6+ with modified alga followed initial Cr6+ concentration ＞ initial pH ＞ modified green alga dosage and the best conditions were initial Cr6+ concentration 80 lng/L,initial pH 5 and modified green alga dosage 0.4 g,the maximum adsorption capacity was 19.19 mg/L.关键词
