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

Table 1

Molecular weight distribution of activated sludge biopolymer (ASBP). MW fraction was calculated based on the band intensity of each protein band of CBB-stained SDS-PAGE gel.

Molecular weight (kDa)	Fraction (%)	Molecular weight (kDa)	Fraction (%)
<3	10.0	30~50	12.4
3~5	0.5	50~60	8.4
5~10	8.6	60~80	3.7
10~20	38.4	80~100	5.4
20~30	8.6	>100	3.9
