NOVELTY - A bacteriostatic glyoxalated polyacrylamide-modified graphene-lanthanum carbonate phosphorus chloride adsorbent comprises 75-87 pts. wt. aminated graphene, 10-15 pts. wt. polyacrylamide, 0.5-3 pts. wt. lanthanum carbonate hydrate, 2-5 pts. wt. glyoxal, and 0.5-2 pts. wt. titanate coupling agent. USE - A bacteriostatic glyoxalated polyacrylamide-modified graphene-lanthanum carbonate phosphorus chloride adsorbent. ADVANTAGE - The glyoxalized polyacrylamide has strong hydrophilicity, and at the same time, a large number of active imide and hydroxyl groups that can form non-metal bonds with numerous substances, such as phosphates and chlorine organic pollutants, through affinity and adsorption, forming bridges between the particles being adsorbed, forming flocs, which are adsorbed by graphene, and removing phosphorus and organic chlorine pollutants, and in the process, inhibiting the growth of bacteria to purify water. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the phosphorus chloride adsorbent which involves preparing glyoxalated polyacrylamide by adding 500 ml distilled water and 200 ml ethanol to a 500 ml three-necked flask, adding 8-15 pts. wt. polyacrylamide and 2-5 pts. wt. glyoxal into the flask, slowly adding 0.4 mol/L dilute sulfuric acid dropwise to the flask until pH is 3-4, placing flask in oil bath, heating to 110-115 degrees C, stirring for 12-15 hours at a constant speed, adding sodium carbonate when reaction is complete to quench until pH is 7-8, filtering material to obtain white flocculant, passing through 2500-3500 ml distilled water, and washing to completely remove sulfuric acid, sodium sulfate, sodium carbonate, and impurities and obtain pure glyoxalated polyacrylamide; preparing glyoxalated polyacrylamide-lanthanum carbonate hybrid polymer by placing 0.5-3 pts. wt. lanthanum carbonate hydrate and glyoxalated polyacrylamide obtained in step (1) in a high-speed and high-energy planetary ball mill, mixing and grinding for 2-3 hours to obtain white fine powder mixture, placing in hydrothermal reactor, adding 100 ml distilled water and 150 ml ethylene glycol, placing in oven at 145-155 degrees C, reacting for 6-8 hours, filtering through a Buchner funnel, washing with 3000-3500 ml distilled water to remove ethylene glycol, placing obtained solid materials in oven to heat to 80-85 degrees C, and drying for 2-3 hours to obtain white fine powder of hybrid polymer; and (3) preparing the adsorbent by adding 75-90 pts. wt. aminated graphene and 0.5-2 pts. wt. titanate coupling agent into hydrothermal reactor, adding 200 ml ethyl acetate and the hybrid polymer obtained in step (2), placing hydrothermal reactor in heater to heat to 150-155 degrees C for 6-8 hours by which hybrid polymer is fully attached to surface of aminated graphene, concentrating material under reduced pressure through a rotary evaporator to obtain black solid powder, rinsing with 2000-2500 ml distilled water, heating material in an oven to 90-95 degrees C, and drying for 3-4 hours to obtain a black powdery solid.
