摘要
按照标准HJ/T298-2007和HJ/T299-2007,对影响锌浮渣浸出毒性的因素进行了分析研究。结果表明:锌浮渣中Zn的浸出浓度与Cl元素含量呈显著线性正相关关系,Zn浸出浓度超标主要是由于助镀剂中ZnCl_(2)的残留所造成。
According to the standards of HJ/T298-2007 and HJ/T299-2007,the factors affecting the leaching toxicity of zinc scum were analyzed.The results showed that there was a significant linear positive correlation between Zn leaching concentration and Cl content in zinc scum,and the excess of Zn leaching concentration was mainly caused by the residue of ZnCl_(2)in the plating aid.
