the no removal over oxide sorbents (k2o/al2o3 , cao/al2o3 and bao/al2o3) at a loading of up to 25 wt.% was investigated using a synthetic diesel exhaust gas containing  1,000 ppm no, 1000 ppm iso-butane (i-c4h10), 8% o2 and n2 balance. the reactor was operated  at 250 oc to 450 oc for the activity study. no was effectively stored (removal efficiencies between 30-60 %) as nitrate under experimen...

Copper and hexavalent chromium are heavy metals that are harmful to human health. Natural adsorbent chitosan, due to its considerable properties such as the presence of functional groups of –NH2 and -OH, non-toxicity, low cost, and biocompatibility, has gained much attention in pollutant removal. Therefore, in the present study, adsorption of chromium (VI) and copper (II) ions was conducted in ...

Introduction: Discharge of textile wastewater causes the reduction of sunlight penetration, interferes with the receiving waters ecology and damage the environment. The aim of this study was to determine the removal efficiency of reactive blue 19 dye from aqueous solutions by cuttlefish bone powder. Materials & Methods: This study was performed experimentally and in laboratory scale. In thi...

Toxic heavy metals, such as lead (Pb) and cadmium (Cd) are widely used in industry and their accumulation in the living tissues may cause serious health problems and ecological hazards. Twenty four moderately halophilic bacteria isolated from saline environments of Iran were used to study their ability to bioremediation of lead and cadmium. Amongst them, a Gram-negative rod shaped bacterium, de...

High concentrations of nitrogen compounds, such as ammonia observed in the petrochemical industry, are the major environmental pollutants. Therefore, effective and inexpensive methods are needed for its treatment. Biological treatment of various pollutants is a low cost and biocompatible replacement for current physico-chemical systems. The use of aquatic plants is an effective way to absorb th...

Decolorization of aqueous solutions containing ionic dyes (Reactive Blue 19 and Acid Black 172) by a TFC commercial polyamide nanofilter (NF) in a spiral wound configuration was studied. The effect of operating parameters including feed concentration (60-180 mg/l), pressure (0.5-1.1 MPa) and pH (6-10) on dye removal efficiency was evaluated. The response surface method (RSM) was utilized for th...

River bank filtratio filtration (RBF) is one of the novel water abstraction alternatives to tackle poor water quality problem in Malaysia. This study was conducted to investigate the potential use of zeolite and activated carbon as filter media in the laboratory RBF system. Characteristics of the materials were first determined using the surface analyzer and X-ray fluorescence method. Filter co...
