Polysulfone was investigated as an alternative base-polymer for polymer inclusion membranes (PIM’s) that could withstand harsh environmental conditions and have good transport efficiency of metal ions. PIM’s were prepared using polysulfone as a base polymer and Aliquat 336 as a carrier in the absence of a plasticizer. Chromium (VI) was used as standard to study the extraction efficiency of the ...

Solvent extraction of uranium from sulfate liquor acid ore with Alamine 336 two suppliers has been studied. The influence various parameters, such as sulfuric concentration on bearing solutions, 336, and was investigated. decrease efficiency at the plant caused by degradation organic phase. Degradation presence vanadium in ore. Two theoretical stages could extract more than 90% a solution conta...

In computer vision and artificial intelligence, text recognition analysis based on images play a key role in the retrieving process. Enabling machine learning technique to recognize handwritten characters of specific language requires standard dataset. Acceptable character datasets are available many languages including English, Arabic, more. However, lack for Pashto hinders application suitabl...
