| titleOfInvention | Dithizone grafting chelating gel, preparation method and the method for the treatment of mercury-containing waste water |
| abstract | The invention discloses a kind of dithizone grafting chelating gel, be prepared from by the raw material of following mass parts: polyacrylamide gel: 1.0 ~ 2.0 parts, formaldehyde: 2.0 ~ 3.5 parts, dithizone solution: 0.1 ~ 0.2 part, distilled water: 94.5 ~ 96.8 parts, the quality sum of above each raw material is 100 parts.The preparation method of dithizone grafting chelating gel: the polyacrylamide gel of formula ratio is added in the distilled water of formula ratio and make it dissolve, regulator solution pH is 9 ~ 11; In solution, add the formaldehyde of formula ratio, then in bottle, dropwise drip the dithizone solution of formula ratio, under 24 DEG C ~ 36 DEG C conditions, react 120min ~ 180min, separated product, oven dry, obtain dithizone grafting chelating gel.The method simple for process, the dithizone grafting chelating gel prepared has high absorbability for heavy metal contamination ion, has the removal of mercury rapidly and efficiently for heavy metal wastewater thereby. |
