Abstract

According to the determination method of titration after distillation in Appendix C of JC 1066-2008 "Limits of Harmful Substances in Building Waterproof Coating", 5g sample was dissolved, the pH of solution was adjusted to alkaline, ammonia was distilled from alkaline solution, and the distillate containing excess sulfuric acid was titrated with sodium hydroxide standard solution. In order to explore whether the experimental factors in this standard affect the determination of ammonia content in waterproof coating, this paper carried out several validation tests on sample type, distillate temperature and pH factors.
