Determination of some trace elements in different vinegar samples from Libyan market using inductively coupled plasma atomic emission spectrometer ICP-AES

الملخص EN

Ten vinegar samples were collected from the Libyan local market in the city of Tripoli.

The elements have been investigated were: As, Pb, Cu, Fe and Zn The samples were treated and prepared according to Indian standard IS 14703-1999, and the measurements have been done by using inductively coupled plasm - atomic emission spectroscopy (ICP-AES) available in the Libyan Petroleum Institute.

The analysis indicated that the concentration of Arsenic of all the samples was less than 0.02mg/kg whereas, the concentration of lead is less than 0.03mg/kg.

The concentration ranges of Cu, Fe and Zn were 0.11-0.59mg/kg, 0.72-2.67mg/kg and 0.08-0.28mg/kg respectively.

The concentrations of the elements AS, Pb, Cu, Fe and Zn are within the limits of a variety of standards such as Libyan, Indian and Pakistani ones.
