摘要
通过合成铁氧化物对水体中重金属镉离子的吸附试验研究,结果表明:在单因素吸附试验中,pH值是影响吸附率的主要因素;葡萄糖的存在促进了铁氧化物对Cd2+的吸附,浓度越高吸附效果越好;共存离子NaC l促进了铁氧化物对镉的吸附,并且,在一定的浓度范围内达到吸附最大值。
Through the synthesis of iron oxides in cadmium ion adsorption experiments,the results showed that the adsorption of single factor experiment,pH value is the main factor affecting the adsorption ratio,The existence of glucose to promote iron oxide,concentration of adsorption Cd 2＋ higher adsorption effect better,NaCl ionic promotes the coexistence of cadmium adsorption of iron oxides and,in certain concentration range reach maximum absorption.
