| titleOfInvention | A kind of preparation method of the chelating agen processing heavy metal in waste water |
| abstract | The invention discloses the preparation method of a kind of chelating agen processing heavy metal in waste water, belong to technical field of waste water processing, the method operating procedure is as follows: the Rhizoma Nelumbinis slag that (1) obtains after Rhizoma Nelumbinis is carried out starch isolation obtains lotus root fibre element through synthesis, it is added thereto to deionized water, it is adjusted to the solution that concentration is 0.15g/ml, all N, N' methylene-bisacrylamide and γ aminopropyl triethoxysilane are added reaction in solution obtain modified cellulose so that every 100ml solution to add the amount of 1 5g in solution；(2) adding ethylenediamine, triethylene tetramine in modified cellulose, reaction obtains amination cellulose；(3) adding ethylidene glycol in amination cellulose, sodium hydroxide and Carbon bisulfide reaction obtain cellulose chelate agent.The present invention is by being modified process to natural polymeric chelant so that it is the heavy metal ion in capture waste water, and the heavy metal after process can reclaim, it is to avoid secondary pollution, is effective method of wastewater treatment. |
