The purification and concentration of enzymes by adsorption on charcoal, tannin, aluminum hydroxide, ion exchange resins, and so forth, has been an established practice in the laboratory. Some years before this work was done in 1949, alkali-cooked lignin was used as an adsorbent for mold and malt amylase (Wallerstein et al., 1945). In this paper is described our study of the adsorption of the a...

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 ...

The present review highlights the different types of nano ferrites and their surface modified composites as an alternative adsorbent in waste water treatment. In this review, recent progresses potential applications SFNPs/SFNCs for removal organic inorganic contaminants through adsorption routes are critically reviewed. There number purification techniques but is one simplest, effective economi...

The electric system needs to balance supply and demand on a moment to moment basis. Energy commodities such as coal, oil and natural gas can be readily stored in massive quantities. However, the storage of electricity has been relatively complex and expensive. Today, with the changing ways in which electricity is generated and used, increased penetration of renewable energy sources and smart gr...

Diclofenac is a drug with an analgesic effect that accumulates and results in adverse consequences if it enters the human body more than needed. Low concentrations of diclofenac have been detected in different water sources through leachates of landfills and agricultural areas, human and animal excreta expired drug discharge and hospital effluents. To eliminate diclofenac from the aquatic e...

Oil spills from tanker or oil well have detrimental effects on environment and economy. One of the most economical and efficient methods for oil spill clean-up is mechanical extraction by sorbents which are not only the safest methods but also the least expensive of spill control. The potential use of agricultural by-products such as corn silk for adsorbent of crude oil from water systems was p...

Abstract:  In this study adiffusion based mathematical model was developed to compare the performance of amine-grafted adsorbents with that of 13X zeolite in a fixed-bed adsorption tower which is used to capture CO2 from both humid and dry nitrogen stream under industrial conditions. The results show that the performance of amine-grafted adsorbent and 13X zeolite is almost the same in the dry ...
