Abstract This study reported the results of groundwater quality for drinking and irrigation purposes in Kurukshetra district, Haryana, India. Twelve parameters, namely pH, TDS, TH, sodium (Na+), magnesium (Mg2+), calcium (Ca2+), potassium (K+), chloride (Cl−), sulfate (SO42−), bicarbonate (HCO3−), nitrate (NO3−), fluoride (F−) were evaluated Water Quality Index (WQI) was calculated. Based on WQ...
Background: The municipal solid wastes (MSWs) are disposed in open dumps, which have no leachate collection and removal system, in the Caspian region of Iran. Leachate readily reaches the nearby water resources such as streams, rivers, lakes, and sea. Therefore, understanding the quality and quantity of open dump leachate is vital to the proper treatment of leachate. Methods: The leachate samp...
A new series of Mn-based catalysts (Mn-TiO2, Ce-Mn-TiO2, Mn-TiO2-SO42–, and Ce-Mn-TiO2-SO42–) were successfully elaborated using the sol–gel method associated with supercritical drying approach for low-temperature NO-SCR by NH3. The physicochemical properties aerogel powders examined XRD, N2-Physisorption at 77 K, NH3-TPD, H2-TPR, DRUV-Vis spectroscopy. It was shown that all develop essentially...
The hydrogeochemical evolution of Bosten Lake has an important impact on the lake’s ecology and water environment. Kriging interpolation, principal component analysis Piper Gibbs charts were used to analyze hydrochemical characteristics genesis in summer autumn. following are main conclusions: (1) In autumn, hydrochemistry lake follows order SO42− > Cl− HCO3− Na+ Mg2+ Ca2+ K+. (2) concentrat...
The aim of the study was to assess groundwater quality in a rural area affected by abandoned pyrite ash waste dumps. abundance major ions depends largely on nature rocks, climatic conditions, and mobility. To evaluate geochemical processes, 30 samples collected from Valea Calugareasca, Prahova County, Romania, were analyzed for anions (NO3?, SO42?, Cl?, HCO3?, F?) cations (Ca2+, Mg2+, Na+, K+),...
