Solvent Extraction of Zinc with Triphenylphosphite (TPP) from a Nigerian Sphalerite in Hydrochloric
A hydrmetallurgical study based on the extraction of Zn and Pb from a Nigerian sphalerite mineral leached with 4 M hydrochloric acid has been undertaken. Triphenylphosphite (TPP) has proved to be very effective for the extraction of zinc. With 2 M TPP and at ambient temperature of 25±2°C; 35.71% and 66.7% of Pb and Zn were extracted, respectively, into the organic phase within 60 min. The recov...

متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولEvolution of the TPP - dependent enzyme family
The evolutionary relationships of the thiamine pyrophosphate (TPP) dependent family of enzymes was investigated by generation of a neighbor joining (NJ) phylogenetic tree using sequences from the conserved pyrophosphate (PP) and pyrimidine (Pyr) binding domains of 17 TPP-dependent enzymes. This represents the most comprehensive analysis of TPP-dependent enzyme evolution to date. The phylogeny w...
