Abstract
A new highly sensitive spectrophotometric method for determination traces of cadmium using Cd-(II)-KI-Crystal Violet system in the presence of Triton X-100-poly(vinyl) alcohol (PVA) mixture has been developed. The apparent molar absorptivity of the system is 1.77 × 105 1-mol−1 cm−1 and its Sandell's sensitivity is 6.35 × 10−4 μg·Cd·cm2−. Beer's law is obeyed up to 0.32 μg·Cd(II)·ml−1. The method has been applied to determine Cd(II) in waste water, rice and pork meat samples with satisfactory results.
