چکیده
To date, accumulated industrial waste creates serious environmental problems in the regions. Therefore, their processing order to obtain valuable products is an urgent task. As a result of reduction electric smelting phosphorite raw materials Novo-Dzhambul phosphorus plant, about 150-160 kg cuttrel dust formed per 1 ton yellow phosphorus. The resulting considered as secondary material, it can be used phosphoruscontaining mineral fertilizers, since boiler contains proportion and other useful components. purpose this work production - with use sulfuric acid phosphorus-containing fertilizers. Methodology. For under experimental conditions, instrumental test methods were chosen using scanning electron microscope (SEM) Jeol JSM-6490l V brand, multi-parameter portable cyberscanner (PCD 650 Eutech) Q-1500 Derivatograph. Results. According results microscopic studies, was determined that content main component P2O5 range 30-31%. thermodynamic regularities process decomposition help solution have been studied. standard thermal effects changes enthalpy, entropy value Gibbs energy system at temperature 333–363K HSC-6 complex program. mathematical are determine reliability work. optimal technological parameters established determined. Conclusion. A technology has developed for obtaining monocalcium phosphate based from plant solutions. advantage high solubility absorption plants. They also characterized by substances, which ensure growth productivity agricultural plants resistance stress factors.

متن کاملValorization of Phosphorus Secondary Raw Materials by Acidithiobacillus ferrooxidans.
This paper presents the possibility of producing phosphorus fertilizers through Acidithiobacillus ferrooxidans utilization in secondary raw materials solubilization. Phosphorus was obtained from the bones of poultry and fish as well as from Morocco phosphorite. Four doses of poultry bones and fish bones were used in the experiment (2, 4, 10 and 20 g/L) and two doses (2 and 4 g/L) of phosphorite...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...
متن کاملPhase transitions in porous materials: influence of physico-chemical heterogeneities
Essentially all surfaces adsorb fluids due to favourable interactions [1, 2]. For strong enough interactions, chemical bonds may be broken in the adsorbed molecules and/or established between the adsorbent and the adsorbate (chemisorption). For weak interactions, the adsorption process occurs reversibly without breaking any molecule (physisorption). Despite weak, the fluid/substrate interaction...
