there have been increasing interests in finding new and innovative solution for removal of contaminants from soils recently. in the present investigation, electro kinetic (ek) process coupled with activated carbon barrier to remove nickel from kaolinite clayey soil is investigated. laboratory tests were performed by applying a constant voltage to nominal electric field strength of 1 and 1.25 v/...

HNO3-modified activated carbon was used to make electrodes for single-pass capacitive deionization removing F- from drinking water. The optimal operating conditions F¯ removal were studied, and the performance, cycle stability, charge efficiency of electrode investigated. Based on these results, an optimization scheme proposed practical applications. After HNO3 modification, proportion micropor...

In this work, a low-cost activated carbon as well as non-hazardous material, with high adsorption capacity, was prepared from Melia azedarach fruit (MF) by ZnCl2 activation for the removal of Pb(II) toxic metal from aqueous solutions. The microstructure of the activated carbon was observed by Scanning Electron Microscopy (SEM). Batch experiments have been performed as a function of pH, contact ...

The present study aims at investigating the potential of activated carbon AC prepared from waste cotton fiber for the removal of Acid Dyes from aqueous solutions. The prepared activated carbon was characterized by pore structure analysis, Fourier transforms infrared spectroscopy FTIR. Batch adsorption studies were carried out and the effect of experimental parameters such as pH, initial dye con...

−− Benzothiazoles are organic compounds that may produce negative environmental impact when released into watercourses. In particular, 2mercaptobenzothiazole (MBT) are known to be toxic and hard to biodegrade. Activated carbon adsorption and ozonation have been identified as suitable treatment for those contaminants. However, there is some controversy about the effect of carbon surface chemical...

A unique biotechnological method for remediation of industrial wastewater contaminated by toxic mercury, based on the enzymatic reduction of ionic mercury by live bacteria, has been developed by prof. Deckwer and co-workers at GBF (at present HZI), Germany, and implemented in a pilot-plant scale. The experience gained during operation of this installation led to the idea, that the process of bi...

Activated carbon has many applications in the environment, cosmetology, medicine and industry. The surface of each activated can be modified to obtain desired adsorption properties. Chemical activation greatly affect efficiency, control activity application carbon. aim study was modify selected by chemical physical methods, while maintaining these parameters so that it could used medicine. Powd...

powder activated carbon surface (ac) was grinded and modified and altered procedure thorough a facile and easy chemical reaction to appearance of 2-((3silylpropylimino)1-methyl) phenol (ac- (spimp)). subsequently, this novel sorbent efficiently applied for the extraction and preconcentration of some metal ions from real samples. preliminary the influences of variables such as ph, amounts of rea...

Adsorption of 1-Butanol, Phenol, and P-nitrophenol on activated carbon havebeen studied. The results were used to testifying the validity of different modelsbased on thermodynamic principles: Freundlich, Langmuir and Henry isotherms.The maximum capacity of adsorbent for three compounds was determined, Theconstants of equilibrium were determined by Freundlich isotherm and virialisotherm expressi...
