摘要
介绍了在氨 (4mol L) 氯化铵 (1 2mol L) 无水亚硫酸钠 (2 % ) 亚硝酸钠 (0 2mol L)底液条件下 ,银氨络合物在- 0 0 5V处产生一灵敏的吸附催化波 ,银线性范围为 0 5～ 2 0 μg mL ,检出限为 0 2 5 μg mL。本研究还作了催化波性质初探、干扰试验 。
It is reported in this paper that a base solution containing 4 mol/L NH 3·H 2O-1.2 mol/L NH 4Cl-2% Na 2SO 3 and 0.2 mol/L NaNO 2,silver-ammino complex gives a sensitive adsorptive catlaytic wave at -0.05 V.The linear range of silver is 0.5～20 μg/mL.The detection limit is 0.25 μg/mL.Based on this phenomenon,a method for the determination of silver in water is proposed.
