Spectrophotometric determination of boron in plants using monosegmented continuous flow analysis

摘要: A monosegmented continuous flow analysis (MCFA) procedure for the spectrophotometric determination of boron using azomethine-H as colour reagent is presented. Under experimental conditions described calibration graph linear up to 4.00 µg ml–1. The detection limit found 0.02 ml–1, calculated from three times standard deviation blank signal. common interfering elements present in plants were investigated under dynamic MCFA conditions. As expected, iron and copper most severe interferences. This method was used with test samples Plant Sample Exchange Programme (PSEP) Wageningen Agricultural University. results compared favourably those obtained by conventional static published PSEP.
