NOVELTY - Degradation of tetracycline comprises dissolving bismuth nitrate and ferric chloride in nitrate solution, dropping sodium hydroxide solution and adjusting pH to 9-10; adding graphene oxide and ultrasonic precipitating; washing with pure water until neutral, removing supernatant, adding sodium hydroxide solution, dissolving and hydrothermal reacting to get catalytic material; adding hydrogen peroxide and tetracycline-containing organic contaminant solution to light Fenton system reactor; and adding catalytic material and sunlight or UV light irradiating. USE - Method for degrading tetracycline (claimed). ADVANTAGE - The method is simple with good controllability, pollutant degradation efficiency and material stability at low cost.
