摘　　要：本文研究了NaCl等无机钠盐对Cd^(2+)-5-Br-DEPAP-β-CD显色反应的影响,发现它们对此显色体系有不同程度的增敏作用,其增敏作用的顺序为:NaCl>Na_2SO_4>NaNO_3>NaClO_4>NaBr>NaF。从反应微环境的改变,促进包接络合物形成等方面,探讨了这些无机盐对Cd^(2+)-5-Br-DEPAP显色反应增敏作用的机理。The effects of some inorganic sodium salts such as NaCl, NaBr, Na_2SO_4, NaClO_4, NaNO_3and NaF on Cd^(2+)-5-Br-DEPAP-β-CD color reaction Were investigated in detail. The sensitizingeffects of these salts on the color reaction in the order is as follows: NaCl>Na_2SO_4>NaNO_3>NaClO_4>NaBr>NaF. The mechanism of effects of salts on the color rection In the presence foβ-CD was discussed.
