Abstract

The sorption properties of a modified ethylenediamine humate (EDA–H) sorbent toward Co²⁺ and Ni²⁺ metal ions are considered. The results of the influence of sorbent norm (0.05–2.0 g), process time (15–120 min), and metal concentration (0.005, 0.05, and 0.5 g/L) are presented. The advanced extraction of cobalt(II) in solutions with low and medium metal concentrations (0.005–0.05 g/L) and nickel(II) in solutions with a high concentration of cations (0.5 g/L) were detected. Based on the data of physicochemical analysis, it can be assumed that complexation with the sorbent occurred in the course of Co(II) and Ni(II) metal sorption by the sorbent.

不同因素对改性腐植酸钠吸附金属（Co 2+和Ni 2+）的影响

摘要

考虑了改性乙二胺腐殖酸盐（EDA–H）吸附剂对Co ²⁺和Ni ²⁺金属离子的吸附特性。给出了吸附剂标准（0.05–2.0 g），处理时间（15–120 min）和金属浓度（0.005、0.05和0.5 g / L）的影响结果。在低和中等金属浓度（0.005-0.05 g / L）溶液中对钴（II）进行了高级萃取，在高浓度阳离子（0.5 g / L）的溶液中对镍（II）进行了检测。基于理化分析的数据，可以假定在吸附剂吸附Co（II）和Ni（II）金属的过程中发生了与吸附剂的络合。
