Cu²? ion reduction in wastewater over RDF-derived char
Hyung Won Lee, Rae-su Park, Sung Hoon Park, Sang-Chul Jung, Jong-Ki Jeon, Sang Chai Kim, Jin Do Chung, Won Geun Choi, Young-Kwon Park 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.18 8 49-55 (7 pages)
Refuse-derived fuel (RDF) produced using municipal solid waste was pyrolyzed to produce RDF char. For the first time, the RDF char was used to remove aqueous copper, a representative heavy metal water pollutant. Activation of the RDF char using steam and KOH treatments was performed to change the specific surface area, pore volume, and the metal cation quantity of the char. N2 sorption, Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-AES), and Fourier transform infrared spectroscopy... -

Adsorption capability of activated carbon synthesized from coconut shell
Md Shariful Islam, Bee Chin Ang, Samira Gharehkhani, Amalina Binti, Muhammad Afifi 한국탄소학회 Carbon Letters 9 Pages
한국탄소학회 Carbon Letters 2016, Vol.20 1 1-9 (9 pages)
Activated carbon was synthesized from coconut shells. The Brunauer, Emmett and Teller surface area of the synthesized activated carbon was found to be 1640 m2/g with a pore volume of 1.032 cm3/g. The average pore diameter of the activated carbon was found to be 2.52 nm. By applying the size-strain plot method to the X-ray diffraction data, the crystallite size and the crystal strain was determined to be 42.46 nm and 0.000489897, respectively, which indicate a perfect crystallite structure. The... -
A review: synthesis and applications of graphene/chitosan nanocomposites
Hui Yuan, Long-Yue Meng, Soo-Jin Park 한국탄소학회 Carbon Letters 7 Pages
한국탄소학회 Carbon Letters 2016, Vol.17 No.1 2 11-17 (7 pages)
Recently, with continuous developments in the field of materials science, graphene oxide (GO) has emerged as a promising material with excellent electrical, thermal, mechanical, and optical properties, which play important roles in most fields. Researchers have achieved considerable progress with graphene. Chitosan (CS) is a natural polymer that has been studied intensively owing to its specific formation, high chemical resistance, and excellent physical properties. These outstanding properties... -
An overview of new oxidation methods for polyacrylonitrile?based carbon fibers
Hye Kyoung Shin, Mira Park, Hak-Yong Kim and Soo-Jin Park 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 2 11-18 (8 pages)
The process of oxidizing polyacrylonitrile (PAN)-based carbon fibers converts them into an infusible and non-flammable state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor... -
Removal of methylene blue using lemon grass ash as an adsorbent
Harminder Singh, Dawa Tshering B 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2014, Vol.15 No.2 6 105-112 (8 pages)
Wastewater from textile industries is a major cause of water pollution in most developing countries. In order to address the issues of water pollution and high cost for treatment processes, the use of an inexpensive and environmentally benign adsorbents has been studied. The objective was to find a better alternative to the conventional methods. Lemon grass waste (ash) collected from a lemon grass stream distillation subunit in Bhutan was tested for dye removal from aqueous solutions. The study... -
저에너지 마이크로버블 장치를 이용한 고농도 암모니아 공장 폐수 처리
정재억, 정용준 한국습지학회 한국습지학회지 6 Pages
한국습지학회 한국습지학회지 2016, Vol.18 No.3 11 286-291 (6 pages)
고농도의 암모니아 함유 공장 폐수를 대상으로 마이크로버블이 발생되는 장치를 이용하여 암모니아 탈기에 의한 처리 가능성을 평가하였다. 기존 처리장은 pH를 12.5로 유지하면서 반응 조내의 온도를 30℃에서 70℃로 상승시켜 72시간 동안 고온 탈기 시켰을 경우 T-N의 제거효율은 70.3%에서 90.5%로 증가하였다. 온도를 30℃로 유지하면서 유입수 의 T-N 농도가 9,120∼12,955 mg/L인 폐수를 20시간 동안 마이크로버블에 의한 지속적인 접촉으로 상온 탈기 시킨 결과 T-N 제거율을 90.5∼91.9%로 확보하였으며, 운전기간 동안의 pH는...
