In the present study, 45 rainwater samples were collected from February to December 2012 on event basis in East Bokaro coal mining environment. Physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. The average pH value was recorded 6.1 and varied from 5.1 t...

The hydrochemical and isotopic techniques have become one of the most popular successful methods for determining hydrogeochemical features groundwater in recent years. A total 15 samples were collected during wet (March, 2021) dry (August, seasons. An approach with major elements (Cl-, Na+, Mg2+, Ca2+, SO4 2=) multi-isotope (2H, 18O) are used this study to solve geochemical variation salinity B...

2/3 of the reservoir surface area was approximately covered with dense populations of Myriophyllum, Ceratophyllum and Potamogeton species. The headwaters of the reservoir were considered as hard water and had both carbonatic and non-carbonatic hardness. When they were exposed to lentic condition of the reservoir and its intensive photosynthetic activities of macrophyte communities, the bicarbon...

The adsorption of U(VI) from natural mine water (i.e. containing Na+, K+, Ca2+, Mg2+ as major cations, and Cl?, SO42? HCO3? anions) was investigated in dynamic mode using packed column high-capacity sorbents modified by NH2 organic moieties. use columns effective removing trace amounts species water. capacity obtained with amine functionalized SBA-15, a mesostructured silica, compared those com...

Chronic kidney disease with uncertain etiology (CKDu) is an emerging health problem in Sri Lanka, particularly among the dry-zone farming communities that use groundwater for drinking. We investigated quality of area where both high- and low-prevalence clusters CKDu have been recorded. Eighty-four five surface water samples, covering selected region, were collected analyzed major anions cations...

Agricultural production may cause groundwater pollution. This study investigated the characteristics of shallow pollution in a typical black land agricultural area Northeastern China and geochemical behavior major pollutants. A total 27 23 samples were collected for measuring on-site parameters components 2000 2014, respectively. The improved integrated approach was used to assess contamination...

This work demonstrates the potential utility of ferrate(VI)-based advanced oxidation processes for degradation a representative UV filter, BP-4. The operational parameters oxidant dose and temperature were determined with kinetic experiments. In addition, effects water constituents including anions (Cl−, HCO3−, NO3−, SO42−), cations (Na+, K+, Ca2+, Mg2+, Cu2+, Fe3+), humic acid (HA) investigate...

Water quality assessment in pastoral of Tibetan Plateau, which is water sources for about 40% of world's population and the runoff-yield area of Yellow rivers, is very important. In this paper, Xiahe county which belongs to Tibetan Plateau pastoral was investigated. Six parameters(via, chloride, COD, ammonia nitrogen, nitrate, fluoride, sulfate) were selected to assess the water quality and hea...

Viscosity, electrical conductivity and deposit weight were determined for Electrophoretic deposition (EPD) Mg2+-, Y3+-, La3+- and Ce4+-doped alumina's ethanolic suspensions prepared at dopant concentration between 350 to 1350 ppm. The concentration of XCly (X, y were: Mg, 2; Y, 3; Ce, 3 and La, 3, respectively) the charging salt, is also found to be a critical factor to control the viscosity. I...
