Garlic (Allium Sativum) is a major crop in Hamadan Province. However, adequete information on K status in this region is not available and no suitable extracting solution can yet be introduced. This experiment was carried out to determine the available K level in 10 soils from Hamadan region. The treatments included two K levels (0 and 200 mg K /kg soil as K2SO4) and 10 Soils in a factorial exp...

in this research, several chemical extractants and modified olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (p) for corn (zea mays l.) plant. in this experiment, the highest correlation was obtained between extracted p by olsen and colwell methods (nahco3-extractable p) and dry weight of corn shoot (r =0.67 and 0.75, p
Background: In nuclear technology, the solvent extraction is an important step for recovery of rare earth materials, purification, radionuclide production, and preparation of nuclear reactor materials. Tributyl phosphate (TBP) and toluene are taken as extractant and diluent, respectively, for study of extraction efficiency for rare earth element like CeO2. Methods: In the present paper, idea of...
The present work describes the results of research a complex substances obtained from sedimentary wine yeast by extraction with food extractants use ultrasound. filtrates alcoholic extracts and sediments isolated filtrate were investigated. It has been shown that hydrophobic moderately soluble poorly in alcohol, such as ethyl esters fatty acids, phospholipids, sterols, squalene, alcohol-contain...
Abstract A series of neutral organophosphorus extractants, comprising phosphine oxides, phosphinates, phosphonates and phosphates with linear branched alkyl chains have been synthesized. Together some similar commercial the performance these new compounds in extraction Nd(III) Dy(III) from both aqueous nitrate non-aqueous ethylene glycol solutions was investigated. It observed that: (1) order e...
Pillar[5]arenes, as a new intriguing class of calixarene analogues, were functionalized with ten diglycolamide (DGA) arms on both sides (rims) of the pillar framework and evaluated for their extraction behaviour towards Am(III) and Eu(III). These novel extractants exhibit excellent separation and extraction efficiency, suggesting its significant potential for nuclear waste remediation. Laser in...
