| titleOfInvention | The preparation method of a kind of modified ramie adsorbent and application |
| abstract | The present invention relates to preparation method and the application of a kind of modified ramie adsorbent, concretely comprise the following steps: the raw-material pretreatment of (1) ramee: ramee is pulverized, sieve, go wax and alkalization after standby；(2) chelating agent synthesis acid anhydrides: chelating agent EGTA is in the mixed organic solvents of acetic anhydride and activator in addition, and stirring reaction, standby after filtration drying at 65 DEG C；(3) anhydride modified ramee: the acid anhydrides of pretreated ramee powder with synthesis is added in activator soln, stirring reaction at 75 DEG C, this modified ramie adsorbent can be obtained through washing, being dried.This Adsorbent modification is effective, adsorbent capacity is big, and (maximal absorptive capacity to cadmium ion is 159mg/g, maximal absorptive capacity to lead ion is 274mg/g), adsorption rate is fast, adsorption equilibrium can be reached in 10min, repeatable utilization and non-secondary pollution, be particularly suitable for processing high concentration heavy metal industrial effluent. |
