In this study arsenate [As(V)] removal from drinking water by coagulation process was investigated. Ferric chloride (FeCl3.6H2O) and ferrous sulfate (FeSO4.7H2O) were used as coagulant. The effects of major operating variables such as coagulant dose (1–30 mg/L) and pH (5.5–9.5) were investigated. Ferric chloride and ferrous sulfate were found as effective and reliable coagulant due to required ...

Although its role in mammalian physiology is currently underappreciated, sulfate is an obli‐ gate nutrient for numerous cellular and metabolic processes in human growth and develop‐ ment [1].The diet provides approximately one third of sulfate requirements in adults [2], although sulfate intake can vary greatly (1.5-16mmol/day) and is dependent on the source of drinking water (negligible to >50...

Two experiments were conducted to investigate the effects of sodium sulfate water and the efficacy of nonnutritive feed additives in nursery pig diets. In Exp. 1, 320 barrows (5.4 ± 0.1 kg BW and 21 d of age) were allotted to 1 of 8 treatments for 24 d in a 2 × 4 factorial with 2 levels of sodium sulfate water (control or 3,000 mg sodium sulfate/L added), and 4 dietary zeolite (clinoptilolite) ...

The ability of sulfate-reducing bacteria to produce hydrogen sulfide and the high affinity of sulfide to react with divalent metallic cations represent an excellent option to remove heavy metals from wastewater. Different parameters have been proposed to control the hydrogen sulfide production by anaerobic bacteria, such as the organic and sulfate loading rates and the feed COD/SO4(2-) ratio. T...

OBJECTIVE Evaluation of the efficacy and safety of a single oral dose of a 1200 mg sachet of chondroitin 4&6 sulfate (CS 1200) vs three daily capsules of chondroitin 4&6 sulfate 400 mg (CS 3*400) (equivalence study) and vs placebo (superiority study) during 3 months, in patients with knee osteoarthritis (OA). DESIGN Comparative, double-blind, randomized, multicenter study, including 353 patie...

The acid tolerance response of an AMD bioremediation system based on sulfate reduction was investigated. Efficient sulfate reduction was observed with a maximum sulfate reduction rate of 12.3±0.8 mg L(-1) d(-1) and easily available organic carbon was released during high acid treatment with an initial pH of 2.0. The rapid increase in sulfate reduction was observed when the extreme acid treatmen...

this study was conducted to evaluate the effect of foliar micronutrients cu, mg and b on quantitative traits in two sesame crop year 1394 was performed farmer field. a split plot experiment in randomized complete block design with three replications. the main factor includes four operating cu sulfate solution, mg sulfate, b sulfate and control (water) and subplots consisted of two sesame (uniqu...

plants are the most sources for cadmium enters to human food and this element in food regime may be a serious threat to human health. thus, the effect of azotobacter inoculum (azotobacter chroococcum), mycorrhiza fungi (glomus intraradaices) , zinc sulphate and urea on cadmium convertation and growth parameters of fenugreek medicinal plant (trigonella foenum gracum l.) in cadmium polluted soils...

The objectives of this research are twofold: (a) to review current methods for rapid analysis dissolved protein in water and wastewater (b) introduce a new spectrophotometrical method determination proteins the 10–2500 mg/L range using carbonate-tartrate reagent, phosphomolybdic-phosphotungstic copper sulfate.
