在盐土中测定氯化物,通常将土壤和水混合,用1:2.5或1:5的比例摇动后过滤,在澄清的滤液中加一定量的硝酸,再用标准硝酸银(0.1N AgNo_3)来滴定氯化物,这个方法在一般的土壤分析书中都可以见到。由于土壤溶液制备的不易,特别是黏重的土壤,过滤很需要时间,并且不易得到澄清的溶液,所以分析的人,往往在制备溶液的一点上,化费了很多时间。 Determination of chloride in saline soil, usually soil and water mixed with 1: 2.5 or 1: 5 ratio of shaking after filtration, in the filtrate to clarify a certain amount of nitric acid, and then standard silver nitrate (0.1NAgNo_3) to Titration of chloride, this method can be seen in the general soil analysis book. Due to the difficulty of preparing soil solutions, especially heavy soils, filtration takes time and the clear solution is not readily available, so the person analyzing often takes a long time to prepare the solution.
