Extraction, separation and spectrophotometric determination of cadmium (II)‎ via onium method

Abstract EN

By application new distinguished method for separation and spectrophotometric determination of micro amount of cadmium (II) in different samples which is called onium method.

And for the majority of this work include the determination optimum conditions for application this method and the study overshadowed optimum values were illustrated the wave length of maximum absorbance for onium species was λmax=260nm, and other optimum values were 0.5M HCl in the presence of 50µg/5mL of Cd2+ by using 1×10-4M of 2,4-dimethyl-3-pentanone at shaking time 15min.

in addition to other effective parameters such as temperature, electrolyte salts, interferences.

So that prepared calibration curve for spectrophotometric determination of Cd(II) in different samples.
