[Determination of abrasive properties of toothpastes by means of copper abrasion].
The results are presented of the investigations of the proposed method for determination of the abrasive properties of toothpastes and raw materials used for their production. The method is based on brushing of copper surface with the studied paste in a device of own design, followed by chemical analysis of copper content in the mass after brushing. The optimal parameters of the work of the abrasive device were determined and the method for determination of copper content is described. For chemical analysis absorption spectroscopy in visible light and atomic absorption spectroscopy were used. The advantages of the proposed method of abrasive force determination was discussed comparing them to those of radioisotope assay.
