工业无机盐产品中,氯化物(以 Cl~-计,以下省略)的测定方法,已有比浊法,银量法,汞量法,硝酸银电位滴定法等,但上述方法在灵敏度,重现性,简化手续等方面尚有不足。特别是对于一些有色或难溶的物质更是欠佳。为此,我们试采用多点增量格氏作图法来测定某些工业无机盐产品中的氯化物含量。 Industrial inorganic salt products, chlorides (Cl ~ - count, omitted below) has been the method of determination turbidimetric method, the silver method, mercury method, silver nitrate potentiometric titration, etc., but the above method in the sensitivity, weight Inaccuracy, simplification and other aspects are still inadequate. Especially for some colored or insoluble material is even less good. To this end, we try to use a multi-point incremental Grignard to determine the chloride content of some industrial inorganic salt products.
