WebMay 1, 2024 · A new material, phosphonium-crosslinked chitosan (PCC), was synthesized for removing Cr (VI) from wastewater via adsorption. THPS was shown to impart phosphonium functionality to chitosan with a relatively simple synthetic procedure, enhancing its adsorption capacity. Equilibrium was achieved within ˜30 min and the … WebMar 31, 2014 · The scheme for the synthesis of HTCC is shown in Figure 1. First, chitosan (6 g, 37.0 mmol) was dispersed in Nanopure water (240 mL) in a 500 mL three-neck round-bottom flask. GTMAC (16.82 g, 21.3 mL, 111 mmol) was added in three portions (7.1 mL each) at 2 h intervals, and the mixture was stirred at 85 °C for 10 h.
