background and objectives: activated carbon is an adsorbent which is mostly employed in order to remove dye from aqueous solutions; however, commercial activated carbon is expensive and this is considered as an obstacle for its usage. therefore, the present study aimed to use waste paper as an inexpensive precursor to produce activated carbon. materials and methods: in the present study, koh wa...

Heavy metal pollution in China’s soil is very serious, and remediation urgent. At present, most of the domestic foreign research aimed at one type for heavy remediation. However, distribution metals effect with chemical agents are different soils. This study committed to investigating WTF on contamination soils based existing laboratory. The influence quality efficiency was analyzed by TCLP lea...

Activated charcoal (AC) can be taken orally as enterosorbent for treatment of pathological states related to exogenous and endogenous intoxications. Synthesized granulated AC with a highly developed active surface (SBET ~2700 m2/g) was used medical countermeasure (MCM) acute radiation sickness (ARS) in rats after total body X-ray irradiation. demonstrates positive results ARS treatment, express...

Increases in ore mining, metal smelting activities, and several other industrial practices in recent times have brought about contamination of soils at higher levels; these have prompted concerns on the consequent effects on the local and global ecosystem. Various remediation technologies have often been sought to meet the challenges. This study therefore seeks to assess the potential of cashew...

High surface area and highly mesoporous activated carbon fibers (ACF) were obtained by physical activation of natural precursors (vetiver roots and bagasse) with steam and chemical activation using phosphoric acid. The textural characteristics of the activated were determined by nitrogen adsorption study and mercury porosimetry and showed that interesting porosity were obtained (SBET up to 1600...

Hospitals are health services that produce waste and sources of pollution for human the environment. dr. Soehadi Prijonegoro Hospital produces most medical in sragen regency still needs cold storage. This research evaluated management hazardous toxicity material medical, solid waste. Life cycle assessment calculations can be performed using a software application, simparo 9.0. scope with gate t...

This paper presents the results of scientific research on structural parameters and adsorption capacity activated carbon obtained from apricot kernels (AC-A) in a fluidized layer. The highlight fact that described procedure allows obtaining mesoporous adsorbent with increased capacities (SBET = 1424 m2/g) quality indices corresponding to requirements enterosorbents imposed by European Pharmacop...

Magnetosensitive biochars were prepared with mechanochemical ball-milling of lignin and blast furnace dust further pyrolysis at 800 °C under an inert gas atmosphere. The physicochemical sorption characteristics the materials analyzed using several techniques: low-temperature nitrogen adsorption–desorption, X-ray powder diffraction, Raman spectroscopy, elemental analysis, potentiometric titratio...

One of the serious environmental problems oil and gas industry is handling spills. Oil spills can be managed by using bioremediation in form biosurfactants. In this research, biosurfactants called U-Champ were used which impact remediation The research conducted was testing effectiveness on Cepu Field contaminated soil reducing TPH heavy metals. method done stirring with various concentrations ...

Heterogenized metalloporphyrin catalysts for oxidation reactions are extensively explored to improve chemical production. In this work, manganese meso-tetraarylporphyrins were immobilized on hydrated mesoporous titanium dioxide (SBET = 705 m2 g−1) through carboxylate or phosphonate anchoring groups separated from the macrocycle by 2-arylimidazole linker fused across one of pyrrolic rings macroc...
