Speciation of Copper in Natural Waters and Its Toxicity to Q67 Freshwater Luminescence Baceria

  • 摘要: 通过铜加标实验,运用两步酸化阳极溶出伏安法(DAM-DPASV)得到官厅水库各水样对铜的络合容量,同时测定了水样在铜加标前后对Q67淡水发光菌的96h急性毒性.官厅水库各水样对铜的络合容量为26~128μg/L,与水样中DOC的含量成正比,络合容量随DOC含量的增加而升高.铜对Q67淡水发光菌的毒性随着水样对铜络合容量的增加而降低,相对于用总铜浓度表示的EC50而言,由电极有效态铜浓度(无机铜浓度)表示的EC50能够更好地预测天然水体中铜对Q67淡水发光菌的毒性.
