Defluorination of groundwater by low-cost adsorbents

Adsorption behavior of petroleum asphaltenes dissolved in Toluene by low-cost mineral adsorbents

This paper presents the feasibility of the removal of asphaltenes from aqueous solutions by using low- cost natural adsorbents such as light expanded clay aggregate (LECA), perlite and bentonite. The structure of adsorbents was characterized by XRD, FTIR, and SEM before and after the adsorption of asphaltenes. The effect of the adsorbent type, initial asphaltene concentration, particle size of ...

Removal of dyes using low cost adsorbents

The low cost adsorbents namely Rice Husk Carbon (RHC), Wheat Straw Carbon (WSC) and Saw Dust Carbon (SDC) have been tested for the effectiveness in decolourisation of wastewater containing a mixture of dyes. Three dyes namely crystal violet, direct orange and magenta have been used for imparting colour in the representative samples of wastewater. Effect of various parameters such as agitation t...

removal of heavy metal ions from polluted waters by using of low cost adsorbents: review

adsorption is a fundamental process in the physicochemical treatment of wastewaters which industries employ to reduce hazardous organic and inorganic wastes in effluents. in recent years the use of low-cost adsorbents has been widely investigated as a replacement for the currently costly methods of removing heavy metal ions from wastewater. it is well-known that cellulosic waste materials can b...

phenolic compounds: health effects and its removal from aqueous environments by low cost adsorbents

Experimental Study on Removal of Chromium by using Cow Dung as Low Cost Adsorbents

In apparent, the intension is removal of chromium using cow dung as low cost adsorbents from the industrial wastewater. Chromium (Cr) is one of the most toxic substances and is introduced into the environment through a variety of industrial activities. In order to remove the chromium from the contaminated water there are lot of methods available, even though they are not in natural way. In the ...
