Application of a graphene oxide for determination of Cadmium, Lead, Copper and Zinc ions at trace level in personal Care Products using Solid Phase ExtractionBy Nusrat Jalbani, Khan Muhammad Malik, Mahboob Ali Rind, Amber . Rasheed, Shahid . Bhutto, Aijaz . Pahnwar, Razia . Begum, Iftikhar . Ahmed, Zulekhan Bibi Bhutto
Abstract: A novel and simple procedure Solid Phase µ-extraction was successfully used as a sample preparation method for the pre concentration and determination of Cd, Pb, Cu, and Zn in different personal care products samples. In the first screening, a five variables were selected with low (-) and high level (+) and were inspected by Plackett–Burman. In order to further optimization, a central 23 +star orthogonal composite design (CCD) was applied …

Spectroscopic determination of toxic elements in various milk samples, collected from different environmentsBy Nusrat Jalbani, Ishratullah Siddiqui, Razia Begum, Farooq A. Khan
Abstract: In the present study, a simple sample preparation method has been established for the determination of toxic elements (TEs) Cd, Cr and Pb in raw milk samples of buffalos and cow. These samples were collected from different locations such as industrial, roadside and near to residential areas of Karachi, Pakistan. Concentrations of understudy TEs were determined by electro-thermal atomic absorption spectrometry (ETAAS) prior to conventional wet acid digestion. The results …
