wastewater contains many organic and inorganic contaminants that can cause serious damage to the environment and health of people, therefore, they have to be eliminated before being downloaded into sensitive areas. different methods of wastewater purification have been used for contaminants removal. however, they present some technical and economic limitations. thus, new methods of nutrients re...

The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...

An experiment was carried out to evaluate and compare the effects of organic and inorganic selenium (Se) sources on broiler male birds (Ross 308). Uniform broiler male chicks divided in to five groups with six replicates were fed with either normal feed (without supplemental Se, negative control), 0.25 ppm of inorganic Se, 0.5 ppm of inorganic Se, 0.25 ppm of inorganic Se + 0.25 ppm of organic ...

In the present study, twenty-five male goat kids (20±2.5 kg BW) were used during an 84- day experimental period to determine the effect of source and level of sulfur supplementation on mohair characteristics and performance. Experimental diets were diets containing 0.18% (as control), 0.24% and 0.34% DM inorganic or organic sulfur. The data were analyzed as a 2 × 2 factorial design. Methionine ...

abstract the objectives of this research was to evaluate the rhizospheric effects of wheat (triticum aestivum l.) on the status of various inorganic p fractions and total organic p in 10 calcareous soils amended with 1% (w/w) municipal sewage sludge from the refinery of shahrekord city under rhizobox conditions. thus, wheat plant was planted in completely randomized design with three replicatio...

In the present paper, nanosized TiO2 supported by zeolite was used in the ozonation of Songhua River as catalyst. The catalytic activity of TiO2/Zeolite for ozonation was testified by nitrobenzene removal, which is one kind of representatively resistant organic contaminant. And the removal of some organic and inorganic compounds existing in the Songhua River by TiO2/Zeolite catalyzed ozonation ...
