表面张力仪在水环境检测方面的应用——结论、参考!
来源:上海谓载 浏览 923 次 发布时间:2021-10-27
四、结论
表面活性剂的水生毒性因环境而异 水硬度和/或吸附剂的存在,但 gtox 值(LC50 或 EC50 下的表面张力)对于每个 表面活性剂。 因此,表面张力可以作为 影响水生毒性因素影响的指标 表面活性剂。 表面活性剂的实验室毒性试验趋于 显示出比自然水环境更高的风险 因为实验室测试通常不考虑表面活性剂对悬浮土壤或沉积物材料的吸附。 如果我们通过以下方式检查自然环境中的水状况 以表面张力测试为指标,我们将能够 将表面活性剂毒性的实验室测试数据与 表面活性剂的自然环境风险。
