Methods for removing pollutants include membrane isolation, ion exchange, precipitation, transformation, and biosorption. Adsorption is a cost-effective method of treating industrial wastewater common commercial concentrating valuable molecules or eliminating contaminants. Banana peel one the largest underutilized agricultural wastes in Malaysia. A novel using low-cost biosorbent made from bana...

Effect of addition of filler material to the natural fiber composite was experimentally investigated. Composites are manufactured by the conventional hand-layup method. All composites are made with a fixed banana fiber with 15% weight fraction addition of different weight fraction of (0, 3, 5, 7.5%) groundnut shell ash is added to the composite. Tensile, hardness, impact and compressive strengt...

BACKGROUND In recent years, proficient treatment of wastewaters containing recalcitrant and toxic compounds such as phenol has been a challenge. This study introduced and evaluated an efficient option for treating such wastewater. METHODS This experimental study was performed on phenol removal as a recalcitrant and toxic compound in aqueous solutions in 2011. The pumice stone was collected fr...

in the present investigation, shells of pistachio are used as adsorbents and they have been successfully used for the removal of blue 56, from water samples. the effect of various parameters such as: ph, amounts of adsorbents, size of adsorbent particles and contact time on removal processing were investigated. in this study freundlich absorption isotherms and langmuir were investigated . the e...

The adsorption ability of Dowex Optipore L493 resin modified with Aliquat 336 (MR), activated carbon modified with Aliquat 336 (MAC) and sawdust modified with Aliquat 336 (MS) for removal of Cr(VI) from aqueous solution in batch system was investigated. The effects of operational parameters such as adsorbent dosage, initial concentration of Cr(VI) ions, pH, temperature and contact time were stu...

Background and purpose: dye is widely used in industries such as cosmetic, leather, paper and textile and release to the environment via their effluents. The purpose of this study was to compare the efficiency of low-cost adsorbents in acid orang 7 dyes removal from water. Materials and Methods: The Rice Stem biomass was sun dried, crushed and sieved to particle sizes in range of 1-2 mm. Then ...

Activated carbons are extremely versatile adsorbents for major industrial significance, especially for metal ions recovery from wastewaters. In this study, the activated carbon prepared from the hard shell of apricot stones, an agricultural solid, which was used for the gold recovery from gold-plating wastewater is investigated. Activated carbon was produced by chemical activation with phosphor...

conclusions the findings of this study showed that the modification of natural zeolites can achieve higher adsorption capacity for organics. in addition, based on the results, natural zeolite being modified with sds as a cationic surfactant had good efficiency for the adsorption of nom. results the results indicated that sds-modified zeolite showed greatly enhanced adsorption capacity. findings...

the electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (mwcnts) is presented. cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (ppo). a redox couple with an anodic and counterpart cathodic peak is obtained. the influence of various parameters such as ph, scan rat...
