Rapid evaporation-driven chemical pre-concentration and separation on paper.
Airflow-enhanced evaporation is investigated as a method for rapid chemical preconcentration on a thin porous substrate. The mechanism is described by combining 1D models of capillary rise, chromatography, and pervaporation concentration. It is shown that the effective length of the column can be shorter than its actual length, allowing concentrate to be held at a stagnation point and then rele...
متن کاملOn-line Pre-Concentration and Separation of Inorganic Arsenic Based on Nano Platinum-Multiwall Carbon Nanotubes
On-line solid phase extraction (SPE) based on nano adsorbent for pre-concentration of inorganic arsenic in water and waste water samples was developed prior to determine by hydride generation atomic absorption spectrometry (HG-AAS). By hydride generation simulation system (HGSS), the inorganic arsenic in liquid samples changed to hydride form and pass through nano platinum multi wall carbon n...

متن کاملConcentration and Separation of Active Proteins from Potato Industry Waste Based on Low-Temperature Evaporation and Ethanol Precipitation
Purpose. Potato fruit juice, a residue of starch industry, contains up to 2.5% [w/w] of proteins that are potentially valuable raw-materials of food, cosmetic, and pharma industries. The recovery of protein from the potato fruit juice is limited by the lack of industrially feasible concentration and separation technologies. The present research thus aimed at development of such process for the ...
متن کاملDeinking of Laser Printed Copy Paper by Chemical Different Treatments and Effect on Optical and Strength Properties of Paper
Paper recycling in an increasingly environmentally conscious world is gaining importance. Withrapid developments in deinking processes for the reuse of secondary fibers being made, therecycling process is become more and more efficient. This work investigated the effect ofchemical different treatments including H2O2 and NaOH on repulping and flotation operationsduring the deinking of laser prin...
