DETAILED DESCRIPTION - A high activity cadmium sulfide photocatalyst comprises 40-60 pts. wt. cadmium acetate, 15-50 pts. wt. thiourea, 5-10 pts. wt. polyacrylamide, 10-15 pts. wt. graphene oxide, 2-3 pts. wt. tin oxide, 1-2 pts. wt. cobalt carbonate, and 5-10 pts. wt. chitosan. The high activity cadmium sulfide photocatalyst is prepared by adding ultrasonic generator with cadmium acetate and thiourea, dissolving in water, adjusting pH to 9-10 with ammonia, sonicating at frequency of 40-60 KHz for 30-60 minutes to obtain suspension; adding another ultrasonic generator with graphene oxide, and dispersing in ethanol to obtain graphene dispersion; and adding ball milling device with suspension, graphene dispersion, polyacrylamide, tin oxide, cobalt carbonate and chitosan, adding water, stirring to obtain paste, drying to 80-100 degrees C for 2-3 hours, grinding into powder, adding to furnace, and calcining to 500-600 degrees C for 2-4 hours.
