mining, metal processing, and petroleum refn- ing [7-13]. Wastewater and sludge produced from these pro- cesses contain various concentrations of copper ions, having adverse effects on the aquatic environment. Copper ions are harmful to human health even at low concentrations, and ab- sorption of excessive copper ions can cause ailments such as Wilson disease [14]. One effective way to remove... 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... -

carbon, dye adsorption, size-strain plot, specifc surface area 1. Introduction In this era of industrialization, industries like textile (especially in the dyeing sector), leather, carpet, rubber, food processing, pharmaceutical, cosmetic, plastic, pulp and paper manufacturing use synthetic dyes regularly and discharge a large amount of dye containing water into the environment [1-4]. Nowaday... 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... -

wastewater. Silica nanoparticles were etched from the graphene CS silica fber by diluted HF solu- tion to produce GO/CS fbers (GO/CS/ETCH). Tests demonstrated that GO/CS/ETCH could remove Congo red from an aqueous solu- tion, which was used as an environmental protection material for re- moving Congo red from wastewater. Li et al. [30] prepared GO/CS composites by wet spinning to treat fuchsin... 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... -

Opera- tion of industrial-scale electron beam wastewater treatment plant.... 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... -

the processing is usually returned to the environment without proper treatment. The textile industry releases huge amounts of colored effuent daily. Wastewater released by these industries pollutes the fresh water of streams, ponds, and rivers, as well as underground water bodies. Dyes are used widely in many industries such as textile production, dyestuff manufacturing, leather tanning, food... 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... -

(4) where Co is the initial dye concentration (mg/l). The RL value indicates the shape of the isotherm to be irreversible (RL= 0), favorable (0< 1), linear (RL= 1) or unfavorable isotherm (RL> 1). By processing the above equation, RL values for investigated MB dye-adsorbent are found to be 0.007 for CCS-1K750 and 0.073 for CCS-1K800. From the values of R L, it is confirmed that prepared carbons ar... -
