Reducing settling rate of post-precipitate in fertilizer solution by chloride addition

摘要: Precipitate settling in ammonium polyphosphate liquid fertilizer solutions containing magnesium, iron, aluminum compound impurities, prepared by concentrating and ammoniating wet process orthophosphoric acid, is impeded addition to the polyphosphate, prior precipitate formation, a source of Cl - amounts sufficient alter morphology crystals such that length-to-width ratio formed increased at least 200%, as compared for absence addition. Since there little propensity longer thinner settle out solution, remain innocuously suspended solution.
