Technological Process of Red Mud Ceramsite for Sb(Ⅲ)Wastewater Treatment
摘要
Abstract
The adsorption property of red mud ceramsite for Sb (Ⅲ)wastewater was investigated,and influencing factors and mechanism of adsorption were also analyzed. The results show that removal rate of Sb(Ⅲ)adsorbed in 100 min in 50 mL 4 mg / L Sb(Ⅲ)solution reaches 99. 25%,when calcination temperature of ceramsite is 1 000 ℃,dosage of ceramsite is 8 g / L,reaction temperature is 25 ℃ and pH needn't adjust. The high correlation coefficient (R2 = 0. 998 7)agrees well with pseudo second-order kinetics. The adsorption of ceramsite on Sb(Ⅲ)can be described well by Langmuir and Freundlich isotherm models. The maximum adsorption capacity is 0. 889 mg/ g based on the analysis of Langmuir model.关键词
