Separation

A new method of separation of carcinogenic aromatic amines in wastewater is given. With SDS (C12H25O4SNa) and β-CD (β-cyclodextrin) addition, it is effective to improve separation. At the same time, it forms mixed micelle. As a result, a micellar electrokinetic capillary chromatography (MECC) system

The paper deals with a novel solar powered water desalination technique based on direct osmosis process. The separation is driven by natural osmosis, which does not require external pumping energy as in the reverse osmosis process. Therefore, the specific power consumption of the desalination proces

The separation of formic (C1), acetic (C2), propionic (C3), and n-valeric (C5) acids in binary water solutions has been studied using a reverse osmosis (RO) membrane pilot plant operating at different temperatures and pressures (usually 21°C and 1.72 MPa). The RO membrane, which is composite, polyam

Commercial polymer cation-exchange resins have been investigated for the separation and recovery of Cu(II) and Ag(I) from synthetic solutions. They contain various ionic species after modification of the cation-exchange resin properties by fixation of organic macro-cations under different experiment

We have used electrodialysis for the separation of amino acids, mineral ions and sugars. It is an important problem at the last stages of biotechnological production of amino acids. We consider two effects that allow one to solve the problem of separations. The “barrier” effect makes it possible to

Separation of benzene and cyclohexane by a NaY zeolite membrane was studied via grand canonical molecular dynamics (GCMD). The GCMD technique was recently developed by simulation methods and effective for the study of the membrane separation process at the molecular level since it can simulate the d

In this study, we investigate the mutual separation of lanthanoids by using a column packed with the microcapsules containing acidic organophosphorus compound as an extractant. It is found that adsorption and elution of lanthanoids are briefly achieved by selecting pHs of the feed aqueous solution.

The separation of mercury from aqueous solutions by complexation–ultrafiltration was investigated. Polyethylenimine (PEI) was used as polymeric complexing agent. Effects of pH and chloride ions concentration on mercury retention were studied. Mercury retention depends strongly on both pH and chlorid
