The present study evaluated the ground water quality and physico-chemical characteristics of the water samples collected from 15 bore wells in the study area which is situated in Rangappa Layout which is located in the Ittamadgu Village of Uttarahalli Hobli which falls in the Bangalore South taluk of the Bangalore Urban district. Physico-chemical characteristics of the collected water samples, ...
Membrane filtration, especially based on the size exclusion phenomenon, has long been established due to its abilities to addressing the growing demands of the clean water of the world’s population. However, widespread applications of the membranes face several challenges including chemical vulnerability, thermal deterioration, and biological degradation of the membranes that transpire while re...
various physico chemical characteristics of the river ganga in varanasi were studied in the oct 2005 to nov 2006. ecological parameters like dissolved oxygen(do), ph, nitrate(no3-), po43- and bacterial population were analyzed and compared with standard permissible limits to assess the best designated use of the river water for various purposes. study revealed that the water quality at varanasi...
Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...
The aim of this study was to assess the impact of trout farm effluent on some physicochemical and characteristics biotic indices in Daryaser River (Mazandaran Province). Sampling of water and macrobentic fauna were done in 5 stations (control, in before influent of farm; and other stations include; in 35, 125, 400 and 750 m after effluent were selected in two weekly in summer, 2011. Results sho...
this paper focuses on the effects of the addition of an ionic liquid, 1-allyl-3-butylimidazilium bis(trifluoromethane sulfonyl)imide ([abim]tfsi), which has a high affinity for benzene, into the poly(vinyl chloride) (pvc) membrane on the pervaporation characteristics of the removal of benzene from aqueous solutions of dilute benzene. when aqueous solutions of 100~500 ppm benzene were permeated ...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
fluorescence chemical sensors for the highly sensitive and selective determination of pb2+ , hg2+, co2+ and fe3+ ions in aqueous solutions are described. the ion sensing system was prepared by incorporating lipophilic ligand (l) as a neutral ion-selective fluoroionophore in the plasticized pvc membrane containing sodium tetraphenylborate or potasium tetrakis (p-chlorophenyl) borate as a liphoph...
