abstract date palm, phoenix dactylifera, is one of the most important horticultural crops in iran. the most soils in iran, especially those cultivated with palm, are calcareous with high ph. the high ph of soil causes reduction of nutrient elements absorption. findings of researches show that application of elemental sulfur along with tiobacillus bacteria in soil, due to sulfur oxidation, reduc...

Syed, M., Soreanu, G., Falletta, P. and Béland M. 2006. Removal of hydrogen sulfide from gas streams using biological processes A review. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 48: 2.1 2.14. Hydrogen sulfide (H2S) is a toxic and odorous compound present in biogas produced by the anaerobic digestion of biosolids and other organic materials. Due to its corrosive nature...

Hexavalent Chromium (Cr(VI)) in water is a public health concern and has been challenging research subject environmental field for many years. Herein, novel composite material consisting of amorphous iron sulfides supported on hydrotalcites (FeS/HTs) was synthesized by “calcination-reconstruction-calcination” process, which enables homogeneous distribution sulfur the surface (HT). The (mass rat...

Background: We intend to study the inhibitory effect of sulfur compound in Ramsar hot spring mineral on tumor-genesis ability of high natural background radiation. Objective: The radioprotective effect of sulfur compounds was previously shown on radiation-induced chromosomal aberration, micronuclei in mouse bone marrow cells and human peripheral lymphocyte. Ramsar is known for having the highe...

In this research, adsorption of dibenzothiophene (DBT) as a model of sulfur containing material has been studied by Pb exchanged Y-zeolite under different experimental conditions. The adsorption was kinetically fast and high adsorption capacity was obtained. The equilibrium adsorption data were analyzed using Langmuir and Freunlich isotherm models. The corresponding parameters and correlation c...
