Use of capillary electrophoresis for analytical control of phthalate and acetate ions in the circulated water in the synthesis of lead(II) nickel(II) phthalate

Abstract

The method for determination of phthalate–and acetate ions content in return water of lead II–nickel–phthalate synthesis (LNP product) was developed. It was used the capillary electrophoresis method based on migration and separation of the mixture components in a quartz capillary subjected to electric field due to their different electrophoretic activity. This method allows to determine phthalate–and acetate ions content in the range from 20 to 200 mg/dm³. Developed method is recommended for analytic control of phthalate–and acetate ions content in return water of of LNP product to adjust it and return to the technological cycle.
