Modeling phosphate adsorption of semi-intensive shrimp pond sediment
Models to simulate phosphate adsorption could be useful for predicting water quality and for controlling eutrophication of ponds and lagoons. The different models of phosphate dsorption of aquaculture pond sediment were investigated, including kinetic adsorption models and adsorption isotherm models...
