| titleOfInvention | Calcined anionic clay visible-light catalyst and preparation method and purposes thereof |
| abstract | The invention discloses a calcined anionic clay visible-light catalyst and a preparation method and purposes thereof. The catalyst is prepared by the following steps of preparing mixed solution of metal salts and urea; heating the mixed solution to the temperature of between 100 and 120 DEG, reacting for 36 to 54 h, and obtaining acidic turbid liquid of which the pH value is between 6.0 and 6.5; centrifuging the acidic turbid liquid, taking precipitation out, washing the precipitation by deionized water until the pH value is neutral, and dewatering and drying; and grinding the dried precipitation, calcining the precipitation at the temperature of between 400 and 900 DEG C for 4 to 6 h, and thus obtaining the calcined anionic clay visible light catalyst, wherein the metal salts comprise divalent metal salts and trivalent metal salts. The prepared calcined anionic clay visible light catalyst can catalytically degrade organic wastewater in visible light, ultraviolet light equipment is not required, a feeding ratio is low, the degradation time is short, and the calcined anionic clay visible-light catalyst has low energy consumption and high efficiency and is suitable for the treatment of medium and low-concentration industrial wastewater. |
