Die polarographische Bestimmung kleiner Selenmengen

The voltammetric deposition and stripping of selenium at gold electrodes

“…Boch and Kau (24), and other workers (34) have evaluated various supporting electrolytes for the polarographic determination of Se(IV). Optimum sensitivity and accuracy are obtained in an NH^Cl-NH^OH buffer at pH 8 -9 containing 0.001 -0.003% gelatin for maxima supression (80).…”
