Abstract

The effects of acid concentration, acid/rock ratio, and fineness of grinding on the interaction between Moroccan phosphate rock and sulphuric acid, in the preparation of superphosphate, have been studied.

An organic‐solvent technique has been used to follow the course and the rate of the chemical reactions. This method has been adopted because the precise composition of the superphosphate cannot be found by the analysis of water extracts, since interaction occurs between unchanged phosphate rock and free acids during the extraction.

Results are given in the form of Tables and graphs.

It is considered that one requirement (among others) for the Dubinin equation to linearise adsorption isotherms of carbons is the forces of adsorption should be essentially non-polar, Van der Waals forces. To test this assumption molecules with permanent dipoles, e.g. NH3 and H2S have been adsorbed

Recent work has shown that auxins such as ,%indolyl acetic acid in sufficient quantity are toxic to plant life and therefore from this point of view it is reasonable that there should be a mechanism within the soil, such as the one just postulated, which would prevent the proportion of natural auxin
