摘　　要：建筑用砂需求量很大,砂中的氯对钢筋混凝土有腐蚀作用,对氯的含量有严格控制。因此对氯含量的检测势在必行。此方法为氯离子在1.5%硝酸介质溶液中与银离子生成白色脱粒,借以比浊法对氯进行测定。The demand of building sand is very large, the chlorine in the sand has a corrosive effect on the reinforced concrete, and the content of chlorine is strictly controlled. Therefore, it is imperative to detect chlorine content. This method for chloride ion generating white threshing and silver ions in 1.5 % nitric acid medium solution, to the determination of chloride turbidimetry.
