牙膏中主要成分检验实验的综合性研究

Comprehensive Study of Toothpaste Main Component Test Experiment

实验测定了多种牙膏中摩擦剂的种类及其他主要成分,实验结果表明:各种牙膏中摩擦剂分别为CaCO3,SiO2,CaHPO4,Al(OH)3,同时检验了牙膏中的甘油及一些维C牙膏中的维生素C,含氟牙膏中的氟离子,定量测定了一些牙膏中摩擦剂碳酸钙的含量和二氧化硅的含量,对高中实验化学中的牙膏中某些成分的定性及定量检验提供了可行的检测方法。

A variety of toothpaste MaCaJi species and other main ingredients were tested, and the experimental re-sults showed that MaCaJi in all kinds of toothpaste were CaCO3, SiO2, CaHPO4, and Al（ OH）a, while the toothpaste of glycerin and some vitamin C toothpaste contended vitamin C, and fluoridated toothpaste of fluorine ion were determined. Some toothpaste MaCaJi calcium carbonate content and the content of silicon dioxide were got quantitative determination. It provided a feasible detection method for the senior high school chemistry experiment of qualitative and quantitative in-spection of some contents in toothpaste.
