摘要
In pH 5-6 solution copper [Cu(II)]can react on p-dimethylaminobenzylidene rodamine(PDR) to form red compound. beta-correction spectrophotometry was studied to determine trace copper. It can remove the absorption interference of surplus PDR in reation solution to raise the analytical sensitivity. Experiments for samples showed that RSD=2. 9 % and the recovery rate was 87. 7 %-112 %. The minimium concentration of the-determination is 0. 55 mu g/25mL. The method is suited to analyse copper in metals and waste water.
