However, absorption is considered one of the most idea method for Cr(VI) removal. Activated carbon is a low-cost material derived from wood or other organic waste from the shell and coir. As the main constituent of coal is carbo Chromium vi removal from aqueous solution by using silver nano activated carbon n, so all the carbon-rich fuels can be used to make activated carbon. Besides, silver nano particles as a catalyst for modifying activated carbon to iChromium vi removal from aqueous solution by using silver nano activated carbon

In this study, the activated carbon loaded silver nanoparticle (AgNPs-AC) was used as a low-cost THAI NGUYEN UNIVERSITYUNIVERSITY OF AGRICULTURE AND FORESTRYHA THI LAN ANHCHROMIUM (VI) REMOVAL FROM AQUEOUS SOLUTION BY USING SILVER NANO-ACTIVATED C Chromium vi removal from aqueous solution by using silver nano activated carbon s of Cr(VI), contact time and dose of AgNPs-AC on Cr(VI) removal efficiency. The results showed that at pH 4. contact time of 180 min, 20mg AgNPs-AC/25mL of KzCnO? solution with initial Cr(VI) concentration at 5 mg/L were the most suitable conditions for adsorption of Cr VI) from aqueous solutions.
