SAMPLES PREPARATION BY STRONG BASES FOR NEXT DETERMINATION OF GROSS MAINTENANCE AND COEXISTING FORMS OF ANALYTES

 Publications are considered for the last two decades with samples preparation solutions of strong bases for determination of both gross maintenance and maintenance of coexisting forms of analytes. It is rotined that a strong bases environment is suitable for a translation in solution of metals, soluble in this environment or soluble in him in presence EDTA, and analytes, able to form anionic oxoforms. Heating, acoustic and electromagnetic irradiation and addition the suroxide of hydrogen intensify the processes of alkaline dissolution of samples or exception from them analytes.

Keywords: samples preparation, strong bases, gross maintenance, coexisting forms of analytes.
