摘要：
A method for the spectrophotometric determination of Pd(II) has been developed by using furfuraldehyde thiosemicarbazone (FFTSC) as complexing agent. Pd(II) reacts with FFTSC in the pH range 1 to 5 to form yellow coloured solution. The complex shows maximum absorption in a buffer solution of pH 1. lambda(max) is 360.5 nm. The composition of the complex is 1:4(M:L). Beer's law is obeyed in the range 0.170 mu g/ml to 1.703 mu g/ml. The molar absorptivity and Sandel sensitivity are calculated as 3.9911 X 10(4) L mol(-1) cm(-1) and 0.0026664 mu g cm(-2) respectively. The method has been. successfully applied for Pd(II) determination in alloys.
