| titleOfInvention | The method of Cr VI in magnetic cellulose/polyglutamic acid coupling material removal waste water |
| abstract | The invention discloses a kind of methods using Cr VI in magnetic cellulose/polyglutamic acid coupling material Adsorption waste water, the described method comprises the following steps: taking a certain amount of hexavalent chromium wastewater and adjust pH value is 2.0~7.0 (preferably 2.0~6.0, 2.0) optimal is, a certain amount of magnetic cellulose/polyglutamic acid coupling material is added in waste water, additive amount in every liter of waste water is calculated as 0.2g~10g with magnetic cellulose/polyglutamic acid coupling material dry weight, 0~for 24 hours (most preferably 1h~8h) is reacted in the constant temperature oscillator that revolving speed is 100rpm~300rpm, and controlling reaction temperature is 10 DEG C~50 DEG C (optimal is 30~40 DEG C), magnetic cellulose/polyglutamic acid coupling material is separated from solution after the reaction was completed, completion pair The removal of Cr VI in waste water.The present invention has many advantages, such as that at low cost, easy to operate, treatment effeciency is high.Processing present invention can apply to electroplate factory, smeltery, Electronics Factory etc. containing hexavalent chromium wastewater. |
