Determination of Aflatoxin M1 in Milk Powder by Ultrasonic-Assisted Extraction and Dispersive Solid-Phase Clean-up

Determination of Iron Species by Combination of Solvent Assisted-Dispersive Solid Phase Extraction and Spectrophotometry

A simple, rapid and sensitive solvent assisted-dispersive solid phase extraction method was developed for the extraction of iron(II) prior to its spectrophotometric determination. The Fe(II) reacted with 2,4,6-tris(2-pyridyl)-1,3,5-triazine, neutralized with sodium dodecyl sulfate and extracted onto the fine particles of benzophenone which were formed upon rapid injection of a mixture of benzop...

Determination of organochlorine pesticide residues in foods using solid-phase extraction clean-up cartridges.

Fourteen organochlorine pesticide residues in fatty foods were determined using a simple and rapid procedure based on solid-phase extraction (SPE) clean-up cartridges with octadecyl (C18)-bonded porous silica, a tandem C18 and Florisil column, Alumina-N and Florisil. A Florisil cartridge eluted with 12 ml petroleum ether-ethyl ether (95 + 5) was the most efficient clean-up procedure capable of ...

Determination of Aflatoxin M1 in Pasteurized and Traditional Milk in Hamadan Province, Iran

Introduction: Milk is one of the most complete food products that is effective in reducing blood pressure and increasing its beneficial fats, preventing colon cancer and osteoporosis, and providing many nutrients, such as protein and calcium. Therefore, the contamination of this valuable foodstuff and its products is considered as a serious risk to the public health of the community. Aflatoxin ...
