利用絮凝剂沉降悬浮物质检测土壤中的易溶盐

摘要

介绍了利用聚氯化铝吸附沉降土壤样品水溶液中悬浮物质的试验方法，检测了其钙、镁、钾、钠、硫酸根离子，并通过硫酸铝钾吸附沉降土壤样品水溶液中悬浮物质检测氯离子，沉降效果较为明显，检测结果与抽滤制取的浸出液基本一致，方法较为简易。%The thesis introduces the experimental method of using poly-aluminum chloride to absorbing floating materials in subsidence soil sam-ple,examines its calcium,sodium,potassium,magnesium and sulfate ions,and examines chloridion in floating material with aluminum potassi-um sulfate absorbing subsidence soil sample. Furthermore,its examination result is rather obvious. In addition,the examination results are in ac-cordance with the filtered lixivium,and its method is relatively simple.
