This study explored the use of inexpensive materials as alternatives to treat effluents from various industries such as petroleum, metals, food processing, textile, industries as well as municipal wastewaters and has become a global environmental issue.

These effluents containing oil can cause serious detrimental environmental impact on the receptor water bodies and induces detrimental effects to aquatic life. It also causes serious problems to wastewater treatment plants due to its high stability and it can be separated only with the help of chemical clarification. Batch adsorption study was conducted to evaluate efficiencies of two different agriculture wastes as micro sorbent to remove oil from aqueous solution.

The agriculture waste used in this study was Durian Shell (DS) and Banana Pseudostems (BPS).

Durian shell and Banana Pseudostems are naturally occurring plants found abundantly in Malaysia. The durian fruit is a seasonal fruit which emits a pungent smell and is commonly referred to as the “King of Fruits”. The banana fruit is a non seasonal fruit and is found in abundance in Malaysia. A detailed batch study to determine its adsorption equilibrium, isotherm and kinetics was carried out at ambient temperatures, various initial concentrations of oil and stirring time. 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 kinetic data was best fitted to the pseudo-second-order kinetic model. 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 were applied to describe the experimental isotherm and isotherm constants. Equilibrium data fitted well with Freundlich model. Thus it is reasonable to conclude that the adsorption of oil on both adsorbents that consist of heterogeneous adsorption sites are similar to each other in respect of the adsorption phenomenon. Kinetic studies indicated that the sorption of oil tend to follow pseudosecond- order kinetics for the range of studied concentrations.

This study is hoped to give rise to new avenues of exploring the possibility of using inexpensive materials to remove oil from aqueous solution.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
