Conserving water resources and protecting them from pollution are of high account in the natural cycle of our life. This study has tried to determine the refining potential and capacity of water hyacinth (Eichhornia crassipes) in order to remove the cadmium from water, studying the influence of factors such as initial concentration of cadmium, contact time, absorbent mass, and pH. Results have ...

Precious metals (PM) refining from E-waste recycling are based on hazardous hydrometallurgical processes, including cyanide leaching for gold or aqua regia palladium, which generates an important wastewater production. In this paper, we present electrochemical process, low viscous deep eutectic solvents ChCl:EG 1:2 and 1:3. Au Pd deposition parameters, but also palladium speciation were studied...

use of auxiliary elements in refining and betterment of engineering properties of soil have gained attention since a long time ago. nowadays the effectiveness and capability of the soil reinforcing technique for giving proper practical solutions in various projects have resulted in this technique quickly gaining a place in geotechnical engineering. in this paper, the results of laboratory studi...

in this article, the results of special effects of privatization of iranian gas refining industry with delphi-dematel integrative approach are presented. according to the results of this research in delphi technique base, all together, experts recognize 39 pivotal factors in privatization of the gas refining companies. then by the aids of dematel technique, in previous step, according to expert...

in the present work, deoxidation and refining of 316lvm steel (low carbon vacuum melted) during the vacuum induction melting process was studied. this grade of stainless steel is one of the most important materials in medical applications. vacuum deoxidation by carbon is the first stage of 316lvm stainless steel production process. in this stage, aluminum must be absent to avoid killing the c-o...

The spread of antibiotic-resistant bacteria is a growing problem and a public health issue. In recent decades, various genetic mechanisms involved in the spread of resistance genes among bacteria have been identified. Integrons - genetic elements that acquire, exchange, and express genes embedded within gene cassettes (GC) - are one of these mechanisms. Integrons are widely distributed, especia...

Large quantities of wastewater are generated by the petroleum refining process. Micron-scale emulsion droplets and submicron difficult to remove from oil-refined wastewater, addressing these issues has been a major challenge for researchers. Membrane technology is widely used in water treatment because it very selective effective filtration his research focuses on oil refinery using polysulfone...

rheological properties of chocolate are important in manufacturing process for obtaining high-quality products with well-defined texture and are directly influenced by composition and their refining time. soy protein benefits from nutritional and functional properties to be used in different foods. effects of different replacement levels of skim milk powder by soy flour, (from 0 to 100%) and ba...

in this study,oil was extracted from the liver and visceral fat of patin (pangasianodon hypophthalmus) and refined. the yield of oil after refining was 49.98%. the major yield loss (34.20%) happened during the degumming procedure. fatty acids found in the crude and refined oil were c12:0, c14:0, c14:1, c16:0, c16:1, c18:0, c18:1, c18:2, c18:3, c18:4, c20:0, c20:1, c20:4, c20:5, and c22:6. the d...
