| Abstract:In this study， based on curcumin （Cur）grafted carboxylated cellulose nanocrystal （CCNC） via EDC/NHS coupling method， CCNC-grafted curcumin （CCNC-Cur） sensor and CCNC-Cur compounded with sodium alginate （CCNC-Cur-SA） hydrogel adsorbents for the detection and removal of Pb2+ were prepared. The results showed that the CCNC-Cur sensor had selective adsorption capacity for Pb2+， with Pb2+ detection limit after digitizing the color depth of the sensor using Image J software of 6.25 mg/L. Under the optimized conditions of static adsorption experiment （adsorption time was 105 min， pH value was 5， adsorbent dosage was 0.08 g）， the adsorption capacity towards Pb2+ by CCNC-Cur-SA hydrogel reached 98.3 mg/g. |
