Abstract The present study focused on evaluating the groundwater hydrogeochemical of shallow aquifers in semi-arid areas northern Ethiopia, using geospatial modelling and multivariate statistical techniques. Physico-chemical parameters, including pH, major ions, electrical conductivity (EC), total dissolved solids (TDS), hardness (TH), pollution index (PI) other from 22 samples have been used t...

Although barley (Hordeum vulgare L.) is regarded as salt tolerant among crop plants, its growth and plant development is severely affected by ionic and osmotic stresses in salt-affected soils. To elucidate the tolerance mechanism, growth and ion uptake of three barley cultivars, differing in salt tolerance, were examined under different levels of NaCl, K/Na and NaHCO3 in the root medium. The cu...

with a mean precipitation rate, much lower than that of the world, iran is among the countries that face severe water challenges. the present study has dealt with the evaluation of hydrochemistry of faryab spring water in hormozgan province, iran. four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, ph, and s...

This study is based on the quality of wastewater from Hawassa University surroundings, which was assessed to determine its suitability for irrigation purposes during 2019. Grab samples influent and treated water were taken assessing parameters. The revealed that could be used purpose with some moderate restrictions. Even though Electrical Conductivity (EC) Total Dissolved Solids (TDS) permit ir...

Combined application of organic and inorganic amendments was known to play a significant role in improvement of soil properties. A field experiment was conducted to explore the effects of gypsum, farmyard manure and commercial humic acid application on the amelioration of salt affected (saline sodic) soil. During this study, soil pH, electrical conductivity, sodium adsorption ratio, responses o...

Sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) was employed to study the sorption behaviors of cellulases on microcrystalline celluloses and hardwood pulp. The adsorption and recovery of cellulases from Aspergillus niger and Trichoderma reesei were investigated at 25 °C. Cellulase recovery was conducted by rinsing adsorbed enzymes with sodium acetate buffer, Milli-Q water,...

Abstract In granitic regions, water salinity typically ranges from 30 to 40 mg L −1 at the surface and 300 500 for groundwater. Technogenic activity in Oaxaca has altered concentration chemical composition, which explains occurrence of salinization processes contamination natural waters. To determine physical–chemical composition Atoyac-Verde river, fifty-two samples were collected tributaries ...

Coliphages T1 and T7 of Escherichia coli were absorbed by kaolinite (K) and montmorillonite (M). Maximum adsorption of T7 (96%) to M was greater than that of T1 (84%), but the adsorption of both coliphages to K was the same (99%). Positively charged sites (i.e., anion exchange sites) on the clays appeared to be primarily responsible for the adsorption of T1 to K but only partially responsible f...

The analysis of trace elements and major ions on groundwater wells in Kuala Langat become the aim this paper for purposes to investigate quality be considered as a suitable alternative water source domestic purposes. sampling was conducted thirteen stations wells. samples were taken from which scatter agricultural areas Langat, Selangor. parameters have analyzed calcium, magnesium, potassium, b...
