提出了一种新的测定天然水中痕量磷酸盐的方法--聚乙烯基甲基醚(PVME)。当溶液加热到45℃时，PVME收缩很大，因此磷钼酸孔雀绿聚集体与PVME一起附着在壁上。
A new method of concentration and separation for determining trace amounts of phosphate in natural water, using polyvinylmethylether(PVME), one of the thermally reverse polymers, was provided. When the solution was warmed to 45 °C, PVME shrank greatly, so that the phosphomolybdate Malachit Green aggregate stuck to the walls along with PVME.
