Biosorption is most economical method for removing toxic metals from waste water.The paper presents the results of studies carried out on sorption of zinc ions from aqueous solutions by a coffee industry waste s a low-cost sorbent. It was found that crushed coffee industry waste possess relatively high sorption capacity as 46.05 mg/g, when comparing with other sorbents. The biosorption studies ...

safety performance is the overall performance of the organization safety management system in the operational system of safety. in the present study, the components of safety performance included visible management leadership, employee participation, training, inspection, implementation tools, and maintenance. the objectives of this study were to assess safety performance, and to analyze differ...

The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...

Researchers have turned to search for new materials that will meet all the aerospace industry requirements. When it is almost impossible achieve this with a single material, composite been studied, and there great developments in field. Many elements are used aircraft construction, but aluminum most preferred due its low density, good castability, high strength, corrosion resistance, fatigue st...
