Determination of Eriochrome Cyanin R by PbO Nanoparticles Loaded on Activated Carbon Using of Dispersive Solid-phase Microextraction Method

Various dye compounds with a complex aromatic structure are not mainly biodegradableand nonoxidizable in environment. Their application in textile, dyeing and industries led toexcess amounts of dye-containing wastewater that harmful for human health [1,2].Eriochrome Cyanine R (ECR) is a synthetic anionic dye that its ionic forms can chelate withseveral metal ions [3]. UV-spectrometry method have been usually applied for determinationof dyes in water. Among different Sample pretreatment methods, solid phase microextractionwith high recovery and less consumption of organic solvent can overcome matrix effects [4].In this study, we have been studied dispersive solid phase microextraction (DSPME)preconcentration method using PbO nanoparticles loaded on activated carbon (PbO-NPs-AC)as sorbent for determination of ECR in water sample. Influence of different variables wereinvestigated by central composite design (CCD) [5].
