Backgrounds and Objective: Surfactants are one of the largest pollutants which exist in urban and industrial wastewaters. Large quantities of surfactants have entered to the environment since last decade due to increased use of synthetic detergent in industrial and home consumptions.In this study, the efficiency of UV/H2O2 process in removal of linear alkylbenzane sulfonate (LAS) from aqueous s...
Anionic DBS surfactant can be photodegraded in a TiO2 dispersion and H2O2 solution under an Hg-lamp (15 W) UV illumination or solar exposure. Degradation process has been monitored through cleavage of aromatic moiety. Degradation of the detergent was small when the photolysis was carried out in the absence of TiO2 and H2O2 an...
In order to study the effect of different intercropping combinations on some maize qualitative traits, an experiment was conducted as a completely randomized block design with three replications in Agricultural Research Station, Faculty of Agriculture, University of Tabriz, Iran, in 2006 and 2007. Two maize (Zea mays L.) hybrids (704, 301), vetch (Vicia villosa), bitter vetch (Vicia ervilia), b...
Different pollutants have undesirable effects on aquatic ecosystems, detergent powder is one of the elements in the sewages so study on the effects of this factor on aquatic animals is crucial. The aim of the present study was to investigate acute effects of detergents as potentially dangerous additive to assess mortality effects of this product on some cultured fish. Silver Carp (Hypopht...
Determination of the oligomeric state or the subunit stoichiometry of integral membrane proteins in detergent solution is notoriously difficult, because the amount of detergent (and lipid) associated with the proteins is usually not known. Only two classical methods (sedimentation equilibrium centrifugation and static light scattering) can measure directly the absolute molecular mass of a prote...
