Abstract : The current study reports the development of a liquid-liquid extraction and dispersive liquid-liquid microextraction methods for trace determination of cadmium(II) in various environmental water (Tap, Red sea, waste water of food industry). The established LLE and DLLME spectrophotometric methods for cadmium (II) detection at trace levels were based upon complex formation of the complexing agent 1, 5-di-phenaylcarbazone (DPC) with cadmium (II) in sodium hydroxide media followed by liquid –liquid extractive (LLE) using chloroform and in dispersive liquid-liquid micro-extraction (DLLME) using chloroform as extractant and methanol as disperser solvent. The DLLME method was found more precise, low cost and accurate compared to LLE. Under the optimized analytical parameters, the low limits of detection (LOD) and quantifications (LOQ) were calculated and compared favorably with the reported methods. The method was successfully applied and validated by ICP-OES for trace determination of cadmium in various environmental water samples. The established DLLME offered good sensitivity and selectivity towards cadmium in the presence of other interfering species.
