biostudies-literatureUnknown7(33)Phan PTIn this study, amine-functionalized rice husk ash (TRI-ARHA) was prepared and successfully applied as a multipurpose adsorbent for simultaneous removal of organics (i.e., methyl orange, MO), nitrate, and phosphate in wastewater with adsorption capacities of around 16.6 mgMO/g, 32.9 mgNO₃ ^--N/g, and 13.4 mgPO₄ ^3--P/g. These capacities were superior to those of the other commercially available materials such as activated carbon and ion-exchange resins in both individual and multipollutant adsorption experiments. In addition, the simultaneous adsorption of three components gives a higher adsorption capacity than individual adsorption for each anion (e.g., 1.18 times for nitrate and 1.11 times for phosphate).
