Preconcentration of acrylamide with dispersive liquid-liquid microextraction based on solidification of floating organic drop prior to determination by HPLC
A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol w...
متن کاملRemoval of phosphorus by the solidification refining with Si–Al melts
To discuss the possibility of phosphorus removal from silicon by the solidification refining with Si–Al melts, the distribution of phosphorus between solid silicon and the liquid Si–Al alloy at 1173–1373 K was investigated. In the present study, the distribution of phosphorus was examined by the temperature gradient zone melting method, where a phosphorus containing molten Si–Al zone was passed...
متن کاملNeutron activation analysis of nickel purified by floating zone-refining and anion exchange.
Nondestructive neutron activation analysis was performed on the nickel purified by floating zone-refining and anion exchange. It is found that floating zone-refining in vacuum is effective to remove Na, Sc, Cr, Zn, As, Ag, Sb and Hg through vaporization in addition to elimination of Se, Sb, Ta, Sm and Tb through segregation. Anion exchange method is also effective to separate Fe, Co, Zn, Mo, Hg...
متن کاملDispersive Liquid-Liquid Microextraction Based on Solidification of Floating Organic Drop as an Efficient Preconcentration Method for Spectrophotometric Determination of Aluminium
A rapid, simple, and sensitive dispersive liquid-liquid microextraction based on solidification of floating organic drop (DLLME-SFOD) method coupled with UV–Vis spectrophotometry has been applied for the extraction and determination of trace amounts of aluminium. The aluminium was extracted from the aqueous media containing aluminon and cetyltrimethylammonium bromide (CTAB). After rapid injecti...
متن کاملLiquation and re-solidification in thermo-mechanically affected zone during friction stir spot welding of AZ91 alloy
The present research aims to study the liquation and re-solidification of liquid during friction stir spot welding of AZ91 alloy. Although friction stir spot welding is a solid-state process, the presence of Mg17Al12 intermetallic compounds results in liquation during the welding process. In this study, friction stir spot welding was performed with a tool rotational speed of 2500 rev/min and a ...
