applying nanoporous materials is an appropriate method for improving chemical quality of the water due to high surface area, internal porous structure (porosity), high absorption capability of harmful gases and liquids, and capability of reactivating the surface. therefore, actions were carried out in order to investigate the effect of activated carbon and zeolite on reducing the total dissolve...

We have investigated the textural properties, electrochemical supercapacitances and vapor sensing performances of bamboo-derived nanoporous carbon materials (NCM). Bamboo, an abundant natural biomaterial, was chemically activated with phosphoric acid at 400 °C and the effect of impregnation ratio of phosphoric acid on the textural properties and electrochemical performances was systematically i...

In this paper, we examined the availability of raw woods as glycolic materials. It was found that some wood materials such as bamboo, larch and cherry could degrade glucose. Glucose is degraded to carbon dioxide via an unknown acidic compound. We then examined whether these wood materials could degrade various sugars. Larch, bamboo and cherry show high degradation rates for glucose, galactose, ...

Lignocellulosic waste corresponds to a large percentage of in the world. Over time research has been developed for use these. This can be converted into activated carbon. The objective this scientific article is carry out bibliographic review carried on lignocellulosic and carbon production methods. applied methodology based qualitative approach, which comparison sought obtaining methods, their...

Since a high toxicity of cyanide which use as a reagent in the gold processing plant, thiosulfate has been recognized as a environmental friendly reagent for leaching of gold from ore. After gold leaching process it's important for recovery of gold from solution using adsorption or extraction methods, One of these methods is activated carbon.The loading of gold from industrial thiosulfate solut...

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...

background: the widespread use of toluene and its consequent adverse effects on health and specially its chronic effects on the central nervous system has resulted in many studies being carried out on the methods that can control and reduce toluene vapors in the airflow. the objective of this study is to assess the effectiveness of the catalytic ozonation process in the removal of toluene from ...

in this work, the removal of copper from an aqueous solution by granular activated carbon (gac) in the presence of competitor ions was studied. a batch adsorption was carried out and different parameters such as ph, contact time, initial copper concentration and competitor ions concentration were changed to determine the optimum conditions for adsorption. the optimum ph required for maximum ads...

abstract introduction: due to environmental and human health concerns related to humic acid (ha), mainly leading to disinfection by-products creation, removal or reduction of this matters is a necessary for drinking water suppliers. based on resistive economy map road and move to self-sufficiency, it is necessary to produce our need in water treatment industry. one of the main consumed material...

feasibility of methanolic wastes treatment containing chlorophenol in experimental uasb reactors i.e. r-i and r-ii working side by side constantly for a couple of almost 32 weeks were studied. uasb reactor r-i was initiated by utilizing the digested sludge alone, whereas, the uasb reactor r-ii was startedup by adding an activated carbon of an effective size 1.5-2.5mm to the digested sludge with...
