The objective of this study is to improve the preparation a biosorbent from cocoa pod shell by an experimental plan. shells underwent drying and grinding followed chemical impregnation with sodium hypochlorite. process was optimized based on analysis methylene blue index as function four factors: temperature, mass material, hypochlorite agitation temperature preparation. This plan reveals that ...

An analysis of wastewater samples collected from different industrial regions of Egypt demonstrated dangerously high levels of nickel (0.27-31.50mgL(-1)), chromium (1.50-7.41mgL(-1)) and zinc (1.91-9.74mgL(-1)) in the effluents. Alarmingly, these heavy metals are among the most toxic knownones to humans and wildlife. Sixty-nine Actinomycete isolates derived from contaminated sites were evaluate...

Potato peels which are a low cost, renewable agroindustry by-product were used for the removal of hexavalent chromium from aqueous effluents. Batch experiments were carried out with an artificial effluent comprising of potassium dichromate in deionised water. The effects of the initial hexavalent chromium concentration, dose of biosorbent, and removal kinetics were explored. An adsorbent dosage...

an agricultural waste and eco-friendly biosorbent i.e. rice husk has been used as a cheap adsorbentfor the removal of methylene blue dye from aqueous solutions. the physical properties of the developedadsorbent were characterized using ftir. the study was realized using batch experiments. the effectsof contact time, ph, initial dye concentration, biosorbent dose and temperature were investigate...

Abstract The quality of air is vital for our existence. Increasing industrial development and household activities will increase the risk pollution environmental damage. Some in ambient very toxic lethal. One method that can remove gaseous pollutants adsorption. Previous study about banana plant as adsorbent pollutant, leaves has highest adsorption efficiency value 76.52%. Purpose this to discu...

In this study, Remazol Yellow (RR) removal was investigated by Saccharomyces cerevisiae immobilized on pumice stone. For the immobilization process, a new technic was used and immobilization matrix HCl pretreated pumice stone was added to the growth medium of microorganism. pH, initial biosorbent (Co), and dye concentration (Cb) effect on biosorption were optimized thr...

Adsorption of each of the ions Cu (II) and Ni (II) on Escherichia coli ATCC25922 and Staphylococcus epidermidis RP62A supported by kaolinite clay in a batch system was investigated. Equilibrium adsorption capacity was determined to be a function of the solution pH, contact time, and initial metal concentrations. The results obtained from the adsorption experiments were used to understand the dr...

Environment fortification must require the use of natural products instead of chemicals to minimize pollution. The detoxification of metal pollutants from wastewater by the development of biomaterials having higher affinity, capacity and selectivity had been found to be as an alternative over conventional technologies that were often inadequate to reduce concentrations in wastewater to acceptab...

The ability of a fast growing plant (Basella alba L.) to remove lead(II) and chromium(III) ions from aqueous solutions has been studied in a batch system. The effects of various parameters such as pH, biomass dosage, agitation time; and initial metal concentration were examined and have been found to have direct influence on the uptake of the metals by the biosorbent. Time-dependence experiment...
