Phosphate treatment has emerged as a common approach to immobilise Lead (Pb) in contaminated soils and waste media, relying on the formation of the highly insoluble mineral pyromorphite as solubility-controlling phase for lead.
Phosphate Treatment of Lead-Contaminated Soil can reduce Pb bio-availability in soils.
Generally high analysis phosphate fertilisers created from phosphoric acid are used for lead treatment like Triple Super Phosphate (TSP) and Double Super (DSP).
Pacific Fertiliser sells both these products as well as other lower analysis Phosphate fertilisers in bulk, bulkbag and small bags.
