Durian peel was used for the synthesis of activated carbon used for adsorption of Basic Green 4 dye. Activated carbon was synthesised under either nitrogen (N(2)) atmospheric or vacuum pyrolysis, followed by carbon dioxide (CO(2)) activation. The synthesised activated carbon then was treated with hydrochloric acid (HCl) solution. The results showed that activated carbon synthesised under vacuum pyrolysis exhibited better properties and adsorption capacities than that under nitrogen atmospheric pyrolysis. The HCl treatment improved properties and adsorption capacities of activated carbons. Pseudo-second-order kinetics well described the adsorption of Basic Green 4.
榴莲皮被用于合成用于吸附碱性绿4染料的活性炭。活性炭是在氮气（N₂）气氛或真空热解条件下合成的，随后进行二氧化碳（CO₂）活化。然后用盐酸（HCl）溶液处理合成的活性炭。结果表明，在真空热解条件下合成的活性炭比在氮气气氛热解条件下合成的活性炭表现出更好的性能和吸附能力。盐酸处理改善了活性炭的性能和吸附能力。准二级动力学很好地描述了碱性绿4的吸附过程。
