In recent years, the upgrading of lignocellulose bio-oils from fast-pyrolysis by means ketonization has emerged as a frontier research domain to produce new generation biofuels. Propionic acid (PA) is extensively investigated model reaction over metal oxides, but activity other materials, such phosphates, mostly unknown. Therefore, PA was preliminarily in gas phase both phosphates and oxides Al...

The aim of this study was to evaluate the effect of three different chemical feed phosphates on the blood biochemical indicators and the content of main minerals of bones in finishing pigs. Over a period of 85 days of fattening, monocalcium (MCP, Finnish product), dicalcium (DCP, Polish product) and calcium-sodium (CSP, Russian product) phosphates were used in fattener feeding. The feeding was ...

the sources of groundwater pollution such as, industrial effluents, sewage and extensive farming have lead to agrochemical pollution. mathematical modeling helps to analyze the existing situation, allows forecasting, and to evaluate the effects of changes in the surrounding water quality. the present research has been focused mainly towards understanding the various processes affecting the tran...

Nitrates and phosphates, found in fertilizers, are the most common eutrophication-causing agents. Douglas fir biochar (BC), a syngas byproduct, was treated with different Al/Mg ratios of sulfate (5% w/w metal loading) followed by an NaOH treatment. The greatest phosphate uptake at 25 °C pH 7 attributed to composite Mg/Al 2:1 ratio prepared 13 (AMBC). Batch AMBC optimized for initial pH, equilib...

abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...

Slag and Al/Mg oxide modified Douglas fir biochar (AMOB) were compared for their phosphate adsorbing abilities use individually or in combination simulated agriculture run-off remediation wetlands. Aqueous batch column sorption experiments performed both low-cost materials. AMOB was prepared bulk using a novel green method. Material analyses included XRD, elemental analysis, SEM, EDX, BET. Bioc...

knowledge of the phosphorus (p) forms is essential for understanding the behavior of phosphorus. the aim of this study was to investigate the effect of wheat cultivation on different inorganic p forms of soil. a greenhouse factorial experiment in a completely randomized design was carried out with three replications in 20 soil types and plantation at two levels (with and without plantation). th...
