May 05, 2012 It was found that the amount of phosphate desorption increased with the increase of alkalinity. A desorption of only 0.6 was obtained when the extracting solution was only 0.01 M NaNO 3 solution without added NaOH. About 48 of adsorbed phosphate was desorbed into the solution when the concentration of NaOH increased to 0.1 M.
Oct 01, 2019 Figure 6a shows that the regenerated CMIOPP 13 nanocomposite exhibits high adsorption performance after five cycles and that the phosphate desorption efficiencies remain at 80 after five cycles. The examination of the weight of each recycled adsorbent revealed that the weight lost after each cycle reduces and does not exceed 5.
