Nature's Providence to Combat a Global Problem

Researchers from the Faculty of Applied Sciences UiTM have researched the thorny shell of the durian fruit and the stem of the banana plant and discovered that parts of these plants can be used to treat effluents from various industries such as petroleum, metals, food processing, textile, industries as well as municipal wastewaters.

Researchers from the Faculty of Applied Sciences UiTM have researched the thorny shell of the durian fruit and the stem of the banana plant and discovered that parts of these plants can be used to treat effluents from various industries such as petroleum, metals, food processing, textile, industries as well as municipal wastewaters.

Effluents containing oil can cause serious detrimental environmental impact on the receptor water bodies and induces detrimental effects to aquatic life which has become a global issue. Effluents discharged also causes serious problems to wastewater treatment plants due to its high stability which requires chemical clarification to be neutralized.

Batch adsorption study was conducted to evaluate the efficiencies of two different agricultural wastes as micro sorbent to remove oil from aqueous solution. The agricultural waste used in this study was Durian Shell (DS) and Banana Pseudostems (BPS).

A detailed batch study to determine its adsorption equilibrium, isotherm and kinetics was carried out. Banana pseudostem was found to be more effective than Durian Shell in removing oil from water. Langmuir and Freundlich adsorption model were applied to describe the experimental isotherm and isotherm constants. The role of DS and BPS in the removal of oil from aqueous wastes was investigated.

The researchers concluded that BPS performed exceptionally well to remove oil from aqueous solution as compared to DS. Langmuir and Freundlich adsorption model was applied to describe the experimental isotherm and isotherm constants. Equilibrium data fitted well with Freundlich model. Thus, it was concluded that both agricultural waste displayed adsorption phenomenon similar to each other. This study will enable new avenues of exploring the possibility of using inexpensive materials to remove oil from aqueous solution.
