Abstract
A new method of concentration and separation for determining trace amo
unts of phosphate in natural water, using polyvinylmethylether(PVME),
one of the thermally reverse polymers, was provided. When the solution
was warmed to 45-degrees-C, PVME shrank greatly, so that the phosphom
olybdate Malachit Green aggregate stuck to the walls along with PVME.
