摘要：

Flow-injection spectrophotometric procedures are described for the determination of chloride and bromide using on-line solid mercury(II) thiocyanate and silver thiocyanate minicolumns, respectively. The linear response ranges for chloride and bromide are 0.28 x 10(-4)-8.5 x 10(-4) M and 0.38 x 10(-4)-2.4 x 10(-4) M, respectively. The sample throughout for both systems is 100 h-1. The lifetime of the minicolumns is 50 and 200 injections, respectively.
