Phosphate adsorption
WebAdsorption and Desorption Adsorption is the chemical binding of plant available P to soil particles, which makes it unavailable to plants. Desorption is the release of adsorbed P from its bound state into the soil solution. Adsorption (or “fixing” as it is sometimes called) occurs quickly whereas desorption is usually a slow process. WebThe experiments of phosphate adsorption removal results show that the phosphate removal rates exceed 99%; the equilibrium phosphate concentrations after phosphate removal reaction completely accord with the requirement of national discharge standards of the second category pollution GB 1A (TP = 0.5 mg/L) in China.
