Al-Saidi Chemistry Department, College of Science, Sultan Qaboos University, Muscat, P.O. Box 36, Sultanate of Oman Received 5 October 2015 Accepted 15 May 2016 ♠Corresponding Author E-mail:... H3PO4, was converted to activated carbon (AC) at 500°C under a nitrogen atmosphere. DC shows very low surface area (6.1 m2/g) while AC possesses very high surface area (829 m2/g). The removal of lisinopril (LIS) and chlorpheniramine (CP) from an aqueous solution was tested at different pH, contact time, concentration, and temperature on both carbons. The optimal initial pH for LIS removal was 4.0 and 5.0 for DC and AC, respectively. However, for CP, initial pH 9.0 showed maximum adsorption on... -
Adsorption properties of activated carbon prepared from pre-carbonized petroleum coke in the removal of organic pollutants from aqueous solution

the aqueous adsorbate solution at initial pH of 6.0. Different initial adsorbate concentrations C o expansion leading to the increase of human activity and con- sequently to an increase in environmental pollution. Activated carbon is widely used for separation and purifcation processes involving aqueous solution systems. Cokes are by-products of the petroleum industry. It is well- known that... -

물을 반응매체로 하고 스티렌과 부틸메타크릴레이트 (BMA)를 단량체로 하여 $65^{circ}C$에서 $95^{circ}C$ 사이의 선택된 온도에서 현탁중합을 실시하였다. 소수성 실리카를 안정제로, azobisisobutyronirile (AIBN)을 개시제로 선택하였다. 안정제의 최적 분산은 pH 10에서 이루어졌으며 반응은 pH 7에서 진행하였다. TGA 및 EDS 측정으로 사용한 실리카의 90%는 안정제로 10%는 입자 내로 유입되는 것으로 분석되었다. 안정제의 농도가 증가할수록 평균입경은 감소하였다. 분자량은 안정제의 농도가 1.67 wt%에 이르며 증가하였다.... -

Electrochim Acta, 55, 3904 (2010).... Global warming is rapidly becoming a major concern as a result of the continuing emissions of greenhouse gases generated by the combustion of fossil fuels. To resolve this problem, various studies on efficient energy storage devices have been undertaken. Electronic technologies are increasingly used in electronic products and systems, and they require effective energy storage [1,2]. Supercapacitors are energy storage devices with high power density and long cycle life, and have been spotlighted... -

by K 2CO3 and H3PO4. These results indicate that the adsorption of acid dyes from wastewater onto activated carbon obeys the pseudo- second order kinetic model. 3.3. Efect of pH The pH level of the aqueous solution is an important vari- able for the adsorption of metals onto the adsorbent. The ef- fect of the pH on Pb (II) adsorption by activated carbon modi- fed was studied for pH 3, 4, 5, 6, 7... -

encap- sulation of the phenolic resin with the PMMA component. This technique also provides very good dispersion of the pore for- mer polymer component into the matrix of the carbon precursor polymer component. The spray dried polymer blend sample was then stabilized in an acid solution, neutralized with an aqueous solution of ammonia, and fnally washed with distilled water to render it P H...
