Study on Adsorption Properties of KOH Modified Rice Husk Carbon for Sulfamethoxazole
The purpose of this study was to explore the adsorption properties of KOH modified rice-husk charcoal on sulfamethoxazole.The optimum preparation conditions of KOH modified rice husk carbon are as follows:The adsorption properties of sulfamethoxazole is the best when the ratio of KOH to rice husk carbon is 1∶2;The opti-mum adsorption conditions were as follows:temperature was 5 ℃;dosage was 0.010 g;initial concentration was 80 mg/L and adsorption time was 2 h.Through the formula of quasi-first and quasi-second order dynamics,it is concluded that the process of KOH modified rice-husk carbon adsorption sulfamethoxazole is chemadsorption.According to the 9 orthogonal tests,the influence factors of KOH modified rice husk carbon on sulfamethoxazole were initial concentration,temperature,dosage and time.The response surface analysis showed that the significant effects were initial concentration,time and dosage.
