Embodiment 1
[0030] (1) AgCl / Ag 3 PO 4 preparation of
[0031] First prepare 20ml AgNO 3 solution (0.05mol / L), add 3g of PVP, stir for 60min until completely dissolved, then add 20ml of Na 2 HPO 4 12H 2 O solution (0.0335mol / L) was poured into the above mixed solution, and stirred in the dark until fully reacted. In addition, 5 mL of NaCl solution (0.05 mol / L) was added to the above Ag 3 PO 4 The mixture was stirred in the dark until fully reacted, and the product was collected by centrifugation, washed three times with absolute ethanol and deionized water, and dried in an oven at 60°C for use.
