摘要/Abstract

摘要： 应用交流阻抗法和极化曲线法,研究了两种环境友好型水处理药剂,即聚冬天氨酸(PASP)和钨酸钠的单一配方及其复配对白铜(B10)在3%NaC l溶液中的缓蚀效果.研究表明:单一聚冬天氨酸或钨酸钠配方对B10均具有一定的缓蚀效果,其中聚冬天氨酸以浓度为40 mg/L,钨酸钠以浓度为60 mg/L时的缓蚀效果最佳.总浓度为40 mg/L的两者复配具有更加明显的缓蚀效果并显示出协同效应,其中以聚冬天氨酸与钨酸钠配比为3∶1的缓蚀效果最佳.

Abstract: AC impedance and polarization curve measurements were conducted to study the effects of environ-ment-friendly inhibitors PASP,Na_(2)WO_(4)and their complexes on the corrosion of cupronickel B10 in 3%NaCl solution.The results indicate that PASP or Na_(2)WO_(4)alone does inhibit the corrosion of B10,and most effectiveconcentrations are 40 mg/L and 60 mg/L for PASP and Na_(2)WO_(4),respectively.With the total concentration of 40mg/L for the complex inhibitors,the optimum complex ratio of PASP to Na_(2)WO_(4)was 3:1.The complex of such a combination showed a significantly synergetic inhibition effect on the corrosion of B10.
