摘要

以低浓度Cu2+水溶液模拟重金属离子废水，研究了胶原多肽基表面活性剂（阴离子型CBS和阳离子型C-CBS）对重金属离子废水的沉淀浮选性能。通过单因素实验考察了pH、气速、表面活性剂质量浓度、气浮时间、Cu2+初始浓度等因素对废水中Cu2+沉淀浮选效果的影响。结果表明，CBS和C-CBS均适用于在碱性条件下对金属离子废水进行沉淀浮选，Cu2+的去除率达到90%左右；且随着气速的升高，Cu2+的去除率增加而后趋于不变；随着表面活性剂用量的增加，对CBS，Cu2+的去除率增加，而对C-CBS，Cu2+的去除率反而下降；随气浮时间延长，Cu2+去除率逐渐增加而后趋于不变。研究表明，胶原多肽基表面活性剂可用于重金属离子废水的沉淀浮选。

Abstract

Precipitation flotation behaviors of the collagen-peptide based surfactants (anionic CBS and cationic C-CBS) for removal of heavy mental ions in wastewater were studied using low concentration of Cu2+ aqueous solution as simulated wastewater containing heavy metal ions. Factors of wastewater pH

gas velocity

mass concentration of surfactant

flotation time

and initial Cu2+ concentration were investigated thoroughly on efficacy of the Cu2+ removal. Both CBS and C-CBS surfactants exhibited good performance at alkaline condition

which around 90% Cu2+ were removed. With increase in mass concentration of surfactants

the Cu2+ removal was increased using CBS whereas it was decreased using C-CBS. When the gas velocity or flotation time was increased

the Cu2+ removal was enhanced initially and then plateaued afterwards. These results suggested that the collagen-peptide based surfactants can be used in the precipitation flotation for the removal of heavy mental ions in wastewater.
