| Abstract: | Based on the inhibitory effect of trace tin on the oxidation of acid fuchsine reaction by potassium bromide in dilute H 2SO 4 solution,A mew kinetic spectrophotometric method for the determination of trace tin has been developed.Beer's law is obeyed for tin in the range of 0-0.2/g.m1 -1 ,and the detection limit is 1.6×10 -11 /g.m -1 .The method has been applied to the determination of tin in natural water with satisfactory results. |
