Volume 2, Issue 2 , September 2015, , Pages 63-69

Abstract
  In this work, a procedure for preconcentration of silver using dispersive liquid–liquid microextraction with the reagent dithizone as complexing reagent was developed. At pH 2, silver ions are complexed with dithizone and extracted into the fine droplets formed when mixing carbon tetrachloride ...  Read More

Ion-Pair-based Dispersive Liquid Liquid Microextraction Combined with Flame Atomic Absorption Spectrometry for a Sensitive Determination of Trace Amounts of Nickel in Food Samples

Volume 2, Issue 1 , March 2015, , Pages 1-6

Abstract
  In this study, a sensitive method of dispersive liquid phase microextraction based on ion-pair combined with the flame atomic absorption spectrometry was proposed for the determination of trace Ni(II) using Aliquat 336-chloride as ion pair agent. Several factors which have effect on  the microextraction ...  Read More

Combination of Dispersive Liquid-Liquid Microextraction with Flame Atomic Absorption for Determination of Trace Co(II) in Environmental Water, Egg Yolk and Hair

Soleyman Bahar; Bahare Babamiri

Volume 1, Issue 2 , September 2014, , Pages 115-120

Abstract
  In this work, a procedure for preconcentration of cobalt using dispersive liquid–liquid microextraction (DLLME) with the reagent 1-Nitroso 2-naphtol as complexing reagent was developed. At pH 4, Co(II) was complexed with 1-nitroso 2-naphtol and extracted into the fine droplets formed when mixing ...  Read More
