Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam activation of the biochar using the conventional heating to produce activated carbon. Addition...

Sulphate removal from mine water is a problem because traditional chemical precipitation does not remove all sulphates. In addition, it creates lime sediment as a secondary waste. Therefore, an inexpensive and environmental-friendly sulphate removal method is needed in addition to precipitation. In this study, carbon residues from a wood gasification process were repurposed as precursors to a s...

The functional properties, resistant starch (RS), and glycemic index (GI) of fresh noodles substituted with banana flour (BF) were investigated. When the substitution BF was increased from 0 to 40%, viscoelastic properties increased, while tensile strength elasticity decreased 53.23 26.84 gf 44.65 15.04 mm, respectively. GI reduced 77.05 62.62 RS content 5.56 23.31%. This is considered a very h...

Adsorption of reactive orange 16 by quaternary chitosan salt (QCS) was used as a model to demonstrate the removal of reactive dyes from textile effluents. The polymer was characterized by infrared (IR), energy dispersive X-ray spectrometry (EDXS) analyses and amount of quaternary ammonium groups. The adsorption experiments were conducted at different pH values and initial dye concentrations. Ad...

For the adsorption of copper (II) and zinc ions from polluted water, an efficient inexpensive nanoadsorbent; nickel ferrite-modified montmorillonite nanocomposite was synthesized by co-precipitation mechano-chemically modified with salts iron. The natural MMT, (NiFe2O4-Mod MMT) nanoadsorbent were characterized several techniques including Fourier transform infrared spectroscopy, X-ray diffracti...

Abstract Using graphite powder, chitosan, and diatomite as raw materials, graphene oxide was first prepared by Hummer’s method GO carboxylated modified into hydroxylated (GOH). It then GOH via carboxylation, (DE) the magnetic chitosan (MCS) were supported on blending to generate composite GOH/DMCS. This novel studied determine its methylene blue wastewater adsorption capability. Results showed ...

<p>Pectin extraction from various fruits and its application in food products have been debatable issues for ages. We conducted our research on the biomass wastes of industry, primarily banana (Musa Acuminata) peels, order to develop a modified procedure effective this substance. Banana peels were used extract pectin using alcohol precipitation technique. This investigation's goal is cont...

Pawpaw, banana and watermelon are tropical fruits with short shelf-lives under the prevailing temperatures and humid conditions in tropical countries like Nigeria. Production of wine from these fruits could help reduce the level of post-harvest loss and increase variety of wines. Pawpaw, banana and watermelon were used to produce mixed fruit wines using Saccharomyces cerevisiae isolated from pa...

The presence of trace levels pharmaceutically active compounds (PhACs) in the aquatic environment threatens human health and environment. Metronidazole (MNZ) is a soluble PhAC with low biodegradability, possible mutant carcinogen. This study aimed synthesis, physicochemical characterizations, employment porous amine-modified green-graphene (AMGG) for MNZ removal from aqueous solutions. Response...

In this study, a low-cost bioadsorbent aluminum metal blended with groundnut shell activated carbon material (Al-GNSC) was used for Cr(VI) adsorption from aqueous solutions. Al-GNSC prepared and characterized using Fourier transform infrared spectrometer (FT-IR), scanning electron microscopic (SEM) X-ray diffraction (XRD) to determine its surface morphology. Batch studies were performed the opt...
