Studies in the preparation of /sup 32/P labelled compounds from high grade rock phosphate with high fluorine content. [Water soluble P/sub 2/O/sub 5/, acidulation, curing]

Abstract

The labelled phosphate to be used for crop evaluation studies should have characteristics exactly similar to the industrial product employed in agriculture. For the preparation of /sup 32/P labelled compound from rock phosphate with high fluorine content, a number of parameters have been studied like particle size of the rock, temperature and amount of acid required, the curing time, etc. Because of the high reaction temperature, the curing time is reduced to experimental limits compared to the commercial product. This paper describes a method for the preparation of such a labelled phosphate and this yields a product with about 95% of the phosphate in the water soluble form.
