Hydrochemical properties of groundwater (n = 32) collected from eight Gram Panchayats (GP) in Kushmandi Block South Dinajpur District West Bengal, India and human health risk posed by fluoride (F−) iron (Fe) are reported. About 18% 28.7% the water samples exceeded permissible limits for F− Fe, respectively, as per prescribed potable quality standards WHO Bureau Indian Standards. Total Dissolved...

Groundwater resources along with surface-water meet the needs of urban, industrial, and agricultural sectors, therefore, their quality should be examined. Water indices are useful tools for aquifer management. In this research, groundwater Miandoab Plain in province West Azerbaijan, northwest Iran, purposes was investigated. For purpose, concentrations ions Mg2+, Ca2+, Na+, HCO3−, SO42−, Cl− pH...

Groundwater is a major drinking water resource in arid coastal regions. The groundwater quality of Bosaso city experienced degradation due to rapid urbanization and industrialization. This study was carried out delineate the spatial distribution parameters evaluate suitability for irrigation uses. samples were collected from Plain determine pH, electrical conductivity (EC), total dissolved soli...

The main aim of the paper is to evaluate ferroprecipitates as immobilization agents for removing selected surfactants from aqueous solutions. Two ferro-precipitates based on iron oxides were used. Adsorbents were varied both in elementary composition and mineral composition. Sodium dodecyl sulphate (SDS) was used as a model anionic surfactant. Simultaneous measurements of the surfactant’s adsor...

Over three million hectares of salt-affected soils characterized with high salinity and sodicity caused serious land degradation in Songnen Plain, northeast China. Soil salinity–sodicity heterogeneous distribution under microtopography is usually influenced by several environmental factors. The side direction movement of soil water driven by water from depression is the key factor that aggravat...

the present study was carried out to evaluate the effects of dietary nano-structured zeolite (nz) levels on reduction of aflatoxin b1 (afb1) in the diet of rainbow trout (oncorhynchus mykiss) for 56 days. for this purpose, 270 fish (23 ± 3.7 g) were randomly distributed into 6 groups including c (control), nz0.5 (basic ration + 0.5 % nano-structure zeolite), nz1 (basic ration + 1 % nano-structu...

Neutron reflection and adsorption isotherm measurements have been used to study the adsorption behaviour of hexanoic acid onto α-alumina surfaces. Importantly, the pH dependence of the behaviour has been characterised with a pronounced maximum in adsorption identified at a pH of approximately 5, close to the pKa of the acid. The adsorbed layer is identified as a bilayer, which is reasonable giv...

In this paper we used a previously reported model for examining the adsorption of nonelectrolytes in solution by solid adsorbents to study the adsorption of lithium(I) cations by acid and sodium amberlites, which is an ion-exchange process. Based on the results, both are equilibrium processes and obey a kinetic law with a unity partial order in the Li+ concentration. The kinetic results were us...

An investigation into the effect of sodium on alloxan diabetes was prompted by the following observations. The beneficial effect of sodium chloride for diabetic persons was demonstrated by McQuarrie et al. (1). They found that an increased intake of sodium chloride resulted in a decrease in the fasting level of blood sugar and in glycosuria. Sayers et al. (2) showed that the low glucose toleran...
