杂多酸(Heteropoly-acids)化学是一个范围广且又复杂的化学领域,通常是指二种或二种以上的简单分子的酸组合而成的一类复杂的多元酸的总称。从络合物观点来说,杂多酸是一种特殊的络合物。早在1826年Berzelius首先发现了钼磷酸。嗣后,这个领域的秘密才逐渐揭露开来。至今其应用日广,文献浩瀚,已构成无机化学领域內一个重要的分支。形成杂多酸乃是大多数多元弱酸阴离子的共同特征,作为杂多酸中心形成体的元素几乎遍布周期系各族元素。 Heteropoly-acids Chemistry is a wide and complex chemical field. It generally refers to the general term for a complex class of polyacids composed of two or more simple molecules of acid. From the complex point of view, heteropolyacid is a special complex. As early as 1826, Berzelius first discovered molybdophosphoric acid. Subsequently, the secret in this area gradually revealed. So far its wide range of applications, the vast literature, has formed an important branch of inorganic chemistry. The formation of heteropolyacids is the common feature of most of the polybasic weak acid anions. The elements of the heteropolyacid center formation are distributed throughout the periodic system.
