在直流极谱上研究了氨缓冲溶液中铬——三价砷的催化波。在最佳实验条件下,3×10~(-8)——1×10~(-6)。M铬与催化波高有线性关系。实验证明此波为表面氢催化波。
The catalytic wave of chromium - trivalent arsenic in ammonia buffer solution was studied by direct current polarography. Under the optimal experimental conditions, 3 × 10 ~ (-8) - 1 × 10 ~ (-6). M Chromium and catalytic wave height has a linear relationship. Experiments show that this wave is a surface hydrogen catalytic wave.
