Maga I. Formation, extraction and analytical application of ionic associates of chromium (VI) with the basic dyes

Have been shown perspective use ionic associates of chromium (VI) with cyanic due-stuff for the high-sensitive and selective ex-traction-photo-metric and ionometric determine of chromium (VI), significance molarity coefficient absorption which have been stud-ied condition formation and extraction ionic association chromium (VI) with the main due-stuff, have been determined optimum con-dition extraction, their constitution, constant stability. Have been determined that use salting-out (LiCl, NaCl) as a source ligand raise possibility ionic association chromium (VI) till extraction, selection and sensitive determine. For the first time have been found quanti-tative characteristics electrode property plastifid membrane on the basis of ionic association chromium (VI) with the main due-stuff. Using cyanuc due-stuff devised new high-sensetive selected extrac-tion-photometric and photometric methods determine chromium (VI) in the interval 0,005 - 26 mkg/сm3, cheked for the help analy-sis of sevage, soil, tec hnical solution, medical preparation.
