摘要
报道了铝、镓的 11钨锆杂多酸盐的合成方法 ,用化学分析、电导滴定、IR、UV、XPS、XRD、TG DTA等进行了表征 ,结果表明这两种化合物具有 Keggin结构杂多化合物的典型特征 .此外 ,考查了铝化合物对铸铁在自来水腐蚀介质中的缓蚀作用 .
This paper deals with the methods involved in the synthesis of K 5[(H 2O)Al(or Ga)(ZrW 11 O 39 )]·XH 2O which is charaterized by IR, UV, XRD, XPS, TGDTA and chemical analysis. The results indicated that the complexes are the derivatives of Keggin structure complexes. Their function as corrosion inhibitors of iron is also studied.
