Wet washing is a widely used method for biodiesel purification. However, this technique generates large amount of wastewater that needs to be treated afterward, which costly and time-consuming. Thus, solvent-aided crystallization (SAC) with ultrasonic irradiation as solution movement assistance was introduced. This based on the addition 1-butanol enhance purification via crystallization. During...

Molecularly imprinting technology is a suitable tool for the development of selective materials isolation and separation substances, targeted use. The aim this paper was to compile an overview current trends in preparation MIP (Molecularly Imprinted Polymers). We focused on implementation ecologically acceptable solutions procedures fabrication application MIP, mainly purposes chemical analyses...

In this research paper, a simple and economic ionic liquid-based liquid-liquid microextraction (IL-DLLME) procedure was developed to ensure efficient rapid separation preconcentration of erythrosine from cosmetic food samples. Important parameters such as IL volume, temperature, acetone ultrasonic time pH that may affect the IL-DLLME have been optimized by central composite design (CCD) based o...

a method based on the ultrasound-assisted solidification of floating drop microextraction technique was developed for the spectrophotometric and spectrofluorimetric determination of curcumin in turmeric powder. in this work a small volume of an organic solvent was floated on the surface of an aqueous solution. after sonication the organic solvent is solidified and separated. the effect of extra...
