Synthesis Technology of Amine Surfactant Modified Brewer's Grains for the Adsorption of Cr(VI)

Abstract:

The modified adsorbent was modified by amine reaction with brewer's grains that using epichlorohydrin as etherfying agent,N,N-Dimethyl formamide as dissolvent, triethylenete tramine as cross-linking agent.The simulation of Cr (VI) wastewater as treatment object, through the optimization of synthesis conditions of Cr (VI), the optimal synthesis process was obtained.The results showed, 4 g brewer's grains, add 15 ml epichlorohydrin and 15 ml N,N-Dimethyl formamide stirring 1h at 85 °C. Then added dropwise to 4mL triethylenete tramine, mixing reaction 1h at 85 °C. The maximal absorption rate got 99.81%.The modified brewer's grains of amine surfactant modified is a promising treatment of chromium wastewater biological materials.
