Abstract The present research evaluates the influence of modification smectite clay (BC) on its adsorption capacity anionic dyes from aqueous solutions. Thermal (BC 250), acidic H 2 SO 4 ), and alkaline NaOH) was carried out. clays were characterized by X-ray powder diffraction, energy-dispersive spectroscopy, Fourier transform infrared spectroscopy. Adsorption investigated batch experiments at...

Modification of Java bentonite assists by the multi-step intercalation sodium and ammonium ions under low-temperature preparation. The adsorbent was examined to remove rhodamine B methylene blue dyes in an aqueous solvent. analysis structural changes conducted XRD showed peak shifting from 19.89° 16.1° specific spectra FTIR 2846.93 cm-1 due increase basal spacing intercalation. total capacities...

Extended Abstract The electric power plants all over world using heavy oil as an energy source produce huge amounts of heavy oil fly ash (OFA) as a waste material. As the OFA waste poses a serious challenge in terms of handling and disposal, a sound and professional solution, other than a simple disposal practice, is urgently needed. In this regard, the conversion of OFA into activated carbon (...

industrial effluents, especially the textile industry are discussed as one of the fundamental problems of the environment .dyes are materials with complex structures that enter into the wastewater from different stages of the textile industry. colors are often toxic, carcinogenic and mutagenic. this study investigated the absorption efficiency of reactive red 198 dye from aqueous solutions by p...

Indonesia has many natural resources that have potential as textile dyes. One of these is sappan wood which produces a red color. In coloring there are two methods used, namely the method dyeing and dipping. its development several color results less stable easily faded. To determine feasibility technique picking up material, research will be carried out using experimental testing fastness fabr...

Magnetic chitosan has received considerable attention over the decades due to its low cost, biodegradability, green sources, magnetic intensity. In this review, we reviewed preparation methods of using co-precipitation, cross-linking and electrochemical. Therein methodologies involved in reaction amino groups are facile introduce additional improve anti-swelling layers, mostly an acidic environ...

Fluorescent particles have broad applications in tagging, tracing, and labeling. Fluorescence is typically generated through incorporation of either inorganic or organic fluorescent dyes into the particle s material. While inorganic dyes are typically more stable, their number and compatibility is rather restricted. The large variety of organic dyes makes them attractive for creating fluorescen...
