Spectrophotometric determination of tin(IV) with phenylfluorone and dodecyltrimethylammonium bromide.

BUNSEKI KAGAKU, 1984
The sensitizing effect of dodecyltrimethylammonium bromide (DTMAB) on the spectrophotometric determination of tin (IV) with phenylfluorone was studied. Under the optimum conditions the sensitivity was about twice as high as that without DTMAB. The calibration curve was linear up to 0.20 ppm of tin(1V).
