Measurement of Cadmium Ion in the Presence of Metal-Binding Biopolymers in Aqueous Sample

Figure 2

Comparison of biopolymer-bound cadmium using four different analytical techniques (ISE, dialysis, chelate disk cartridge and ultrafiltration), in 1 L solution (a) BSA; (b) ASBP. The values on the columns represent the percentage of biopolymer-bound cadmium to total added cadmium before adsorption test. Error bars represent observed low and high values for duplicate experiments.
