In this study, removal of Cr(Ⅵ) from synthetic groundwater by adsorption onto commercial activated carbon (CAC) made up of coconut shell is investigated in batch studies. Surface modification of CAC with sulfuric acid is also conducted to evaluate its removal performance. It is evident that CAC chemically modified with sulfuric acid (sulfuric-treated CAC) demonstrates higher Cr(Ⅵ) removal efficiency than non-treated CAC in dealing with contaminated groundwater with the pH is about 7.0, suggesting that sulfuric-treated CAC is suitable for the in-situ remediation of Cr(Ⅵ) contaminated groundwater. Adsorption of Cr(Ⅵ) is strongly affected by pH, the granular sulfuric-treated CAC exhibits the highest Cr(Ⅵ) adsorption capacity at pH 1.5 and the maximum Cr(Ⅵ) adsorption capacity of which estimated with the Langmuir model was 8.24mg/g.

Oily Waste

Malaysia is one of the main crude oil exporters among countries in Association of South East Asian Nations, ASEAN. Therefore, oil is widely used in many sectors, especially in transportation sectors, and it will produce a lot of oil-based waste that will harm environment. Activated carbon can help to treat this waste by using the permeable reactive barrier (PRB) concept. At the same time, Malaysia is also an agricultural based country which produces a massive amount of agricultural waste. In this study, sugarcane bagasse, corn cob and pineapple's core is chosen to produce activated carbon by using furnace heating processing and microwave processing.
