Electroplating wastewater contains various types of toxic substances, such as heavy metals, solvents, and cleaning agents. Carbon foam was used as an adsorbent for the removal of heavy metals from real industrial plating wastewater. Its sorption capacity was compared with those of a commercial ion-exchange resin (BC258) and a heavy metal adsorbent (CupriSorb™) in a batch system. The experimental carbon foam has a considerably higher sorption capacity for Cr and Cu than commercial adsorbents for acid/alkali wastewater and cyanide wastewater. Additionally, cytotoxicity test showed that the newly developed adsorbent has low cytotoxic effects on three kinds of human cells. In a pilot plant, the carbon foam had higher sorption capacity for Cr (73.64 g kg(-1)) than for Cu (14.86 g kg(-1)) and Ni (7.74 g kg(-1)) during 350 h of operation time. Oxidation pretreatments using UV/hydrogen peroxide enhance heavy metal removal from plating wastewater containing cyanide compounds.
电镀废水中含有各种有毒物质，如重金属、溶剂和清洁剂。碳泡沫被用作吸附剂，用于去除实际工业电镀废水中的重金属。在间歇系统中，将其吸附容量与商用离子交换树脂（BC258）和重金属吸附剂（CupriSorb™）的吸附容量进行了比较。实验用碳泡沫对铬和铜的吸附容量比商用吸附剂对酸碱废水和氰化物废水的吸附容量高得多。此外，细胞毒性测试表明，新开发的吸附剂对三种人类细胞具有低细胞毒性作用。在中试工厂中，在350小时的运行时间内，碳泡沫对铬（73.64 g kg(-1)）的吸附容量高于对铜（14.86 g kg(-1)）和镍（7.74 g kg(-1)）的吸附容量。使用紫外线/过氧化氢进行氧化预处理可提高含氰化物化合物的电镀废水中重金属的去除率。
