摘要: 季鏻盐对高氯酸铝溶液中铝的缓蚀作用何祚清,李金良(徐州师范学院化学系徐州221009)1前言为降低以Al(ClO4)3作为电解液的Al-MnO2干电池中Al的腐蚀速率,选用合适的缓蚀剂并对缓蚀机理进行研究是一项有意义的工作。有关季盐对钢铁及锌的缓蚀作用己有一些研究[1,2],但对铝的缓蚀作用尚罕见报导。本工作在1mol/LAI(ClO4)3底液中用微分极化电阻测量技术和交流阻抗法研究三种季盐?...
Abstract:The inhibitive effect of (P-NO2C6H4)N(C6H5)3Br(NPTPHB) and (p-NO2C6H4)P(C6H5)3Br(NPTPPB (CH5-C6H4) P(C6H5)aBr(MPTPPB) and [CH3(CH2)3CH2-C6H4]P(C6H5)3 Br(PPTPPB) on corrosion of aluminium in 1 mol/L Al(ClO4)3 solution at 15~35℃ and the effect of molecular structure of phosphonium salts on inhibitive efficiency were studied by using the differential polarization resistance and electrochemical impedance techniques. The results showed that all the three phosphonium salts inhibited the corrosion of aluminium. The inhibitive effect of the phosphonium salt was greater than that of the quaternary ammonium salt with similar structure. The inhibitive efficiency of the phosphonium salt which has substitution radical of long carbon chain on benzene ring was higher than that for short carbon chain.Their inhibitive efficiencies increased with rising temperature. The phosphonium salts adsorbed chemically on aluminium surface in Al(ClO4)3 solution and their adsorption followed Langmuir isotherm. Possible models of adsorption of MPTPPB and PPTPPB were proposed.
