Effects of Na131I and UO2(NO3)2 on Vibrio Qinghaiensis sp. Q67 (a freshwater luminescent bacterium) were studied in the paper. Relative luminosity (Irel) was used as the tested physiological parameter. About Na131I solution, Four radioactive concentrations were designed. Irel was fluctuated as the activity under 1000Bq/ml and varied irregularly, while three successive stages in the bioluminescent response […]

Three different zeolitic materials derived from coal combustion by-products (CCBs) were used to treat local coal ash landfill leachate at the same power plant. The zeolitc materials properties were characterized in terms of mineralogical composition (XRD), chemical composition (XRF), total carbon content, morphological analysis (SEM), specific surface area (BET method), cation exchange capacity (CEC), loss […]

Dyeing and finishing processes for the textiles are practiced by human beings since ancient time. However, in recent years a lot of attention has put in these processes because of the awareness of sustainability and eco-friendly textiles and garments. Textile processes use many toxic dyes and chemicals. This waste water is discharged into fields, ponds […]

Comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry (GC×GC/TOF-MS) has been used in group-type chemical compositional analyses of gas turbine fuel as this state-of-the-art technique enables a detailed output of fuel constituents. However, it is an unreasonable expectation for one set of operational parameters to yield optimal separation for every fuel type. The aim of […]

Glauconite and kaolin was used as adsorbent materials for iron ion removal from synthetic solutions. Different concentrations of iron solution have been prepared 10, 20 and 30 mg/L. Different doses of glauconite and kaolin were added 0.1, 0.55 and 1.0 g. Statistical design was used to determine the optimum conditions of iron adsorption on glauconite […]

Recently, there have been many studies to decrease environmental pollution around the coal-fired power stations. One of the studies addresses that untreated ash particles cause economic gains for polymer based composites. In this study, free vibration characteristics of bottom ash/epoxy composite beam with respect to 5 and 10%  bottom ash additive is considered for possible […]

The knowledge of moisture transport in porous building materials and components is crucial to predict and avoid several pathologies and is essential to increase the durability. It is easy to know the amount of water that, for example, some material absorbs when in contact with water. However, it is very difficult to determine where the […]

Passive air sampling is a preferred method of air sampling for many applications. Traditionally, this method uses activated carbon as the sorbent and samples are analyzed by chemical or thermal desorption. This research explores the use of carbon nanotubes in the form of a buckypaper as a sorbent for passive sampling by comparing the mass […]

Nano-sized CdS has been prepared by aqueous chemical method using glycine as a capping and stabilizing agent. X-ray diffraction (XRD) analysis of as-synthesized material revealed hexagonal wurtzite structure of CdS with average crystallite size 48.1 nm. The observed FTIR spectra support the template role of glycine in controlling the size of CdS nanoparticles. Photo-catalytic efficiency […]

Recently, the introduction of separation membranes is progressing in the field of sewage and industrial wastewater treatment. The treatment methods with membrane separation have many advantages. Firstly, the sedimentation tank has not been required for the sake of gravity sedimentation. It is possible that the reaction tank become compact. Secondly, suspended solids (SS) can be […]
