Abstract The extraction of aluminium from dilute phosphoric acid with di-2-ethylhexyl (DEHPA) was optimized using response surface methodology. optimization based on the experimental three-level central composite face-centred design (CCF) and conducted real-life samples. three variables included were pH, extractant concentration aqueous to organic phase ratio (AO). Under conditions (pH 2.5, 0.6...

In the present study, the effect of successive milt collection was investigated on spermatological parameters and reproduction successes of wild and cultured endangered caspian brown trout. The milt collection was done 3 times with two weeks intervals. After milt collection, amount of milt was allocated for milt quality evaluation and reminders used for fertilization. According to results, in w...

Sequential injection system (SI system) was used for the pretreatment of a carbon electrode in an anodic stripping voltammetry (ASV) for the determination of arsenic (III). In this research, a screen-printed carbon electrode (SPCE) was used; SPCE was prepared in our laboratory by us. In ASV, SPCE was chosen as a working electrode because SPCE is less expensive, easy to use for a flow cell and s...

Mononethanolamine (MEA)-based absorption-stripping for CO2 capture is studied. Energy demands in this process are dominated by the stripping column. The shortest stripping line distance approach is used to determine minimum energy requirements for the MEA stripping column under various lean loadings. Simultaneous reaction and vapor-liquid equilibrium is assumed and modeled by the direct incorpo...

the present paper concerns on the selective and very efficient transport of thorium(iv) ions from aqueous solutions through an emulsion liquid membranes composed by paraffin and a surfactant, without carrier requirement. the influence of ph of the external aqueous phase, the surfactant concentration in the membrane phase, the type, and concentration of the acid used in the receiving phase, the ...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

The determination of apparent nutrient digestibility and availability coefficients (ADC and AAC) of ingredients is an important process in the formulation of cost efficient diets for fish. Collection of feces by repeated manual stripping is commonly practiced. However, due to the stress and possible physical damage imposed on fish during repeated stripping, this practice may influence ADC and A...

A study on the extraction of Acetaminophen (ACTP) which is also known as paracetamol, from aqueous solution by emulsion liquid membrane process using Taylor-Couette Column (TCC) was investigated. An ELM consists of three phase system which are the external, membrane and internal phases. The external phase containing the ACTP aqueous solution to be treated. Basically, the internal and membrane p...

We present a spatially resolved stellar population analysis of 61 jellyfish galaxies and 47 control observed with ESO/MUSE attempting to understand the general trends populations as function stripping intensity mass. This is public sample from GASP programme, $0.01 < z 0.15$ $8.9 <\log(M_{\star}/M_{\odot}) 12.0$. apply spectral synthesis code FADO fit self-consistently both nebular contribution...
