The sorption performance of a modified carbon black was explored with respect to arsenic removal following batch equilibrium technique. Modification was accomplished by refluxing the commercial carbon black with an acid mixture comprising HNO3 and H2SO4. Modification resulted in the substantial changes to the inherent properties like surface chemistry and morphology of the commercial carbon black ...<br/><br/>Dipu Borah, Shigeo Satokawa, Shigeru Kato, Toshinori Kojima (2008) <i>Journal of Hazardous Materials, In Press, Corrected Proof, Available online 13 June 2008</i> : <br/>

This paper reports the results of the adsorption performance of As(V) removal by a commercial carbon black and its H2SO4-modified form in a single-ion situation. The influence of different process parameters and the physicochemical principles involved were studied in detail. Acid modification caused morphological changes in the virgin carbon black as evidenced by BET surface area measurements and ...<br/><br/>Dipu Borah, Shigeo Satokawa, Shigeru Kato and Toshinori Kojima (2008) <i>Journal of Colloid and Interface Science</i> 319: 1 53-62<br/>

A commercial grade carbon black was chemically modified using mineral acids (either with HNO3 or H2SO4 or mixture) and the sorption performance of the virgin and modified forms were investigated. Chemical modification resulted in the creation of surface acidic functional groups (COOH, SO2OH) and was verified by FTIR spectra. This was further verified by TGA analysis revealing higher weight loss ch...<br/><br/>Dipu Borah, Shigeo Satokawa, Shigeru Kato and Toshinori Kojima (2008) <i>Applied Surface Science</i> 254: 10 3049-3056 <br/>

The desulfurization reaction involving direct electron transfer from potassium ferrocyanide, K4[Fe(CN)6], successfully removed organic sulfur from a subbituminous coal. The temperature variation of desulfurization revealed that increase of temperature enhanced the level of sulfur removal. Moreover, the desulfurization reaction was found to be dependent on the concentration of K4[Fe(CN)6]. Gradual ...<br/><br/>Dipu Borah (2006) <i>Energy Fuels</i> 20: 1 287-294<br/>

The physicochemical factors such as equilibrium time, solution pH, initial concentration of Cd(II), particle size and temperature that control the adsorption of Cd(II) from aqueous solutions onto pyrite has been investigated through batch experiments. Prior to this study, pyrite was characterized through chemical and XRD-analysis. The point of zero charge, pHpzc was determined using the batch equi...<br/><br/>Dipu Borah and Kulakamal Senapati (2006) <i>Fuel</i> 85: 12-13 1929-1934 <br/>
