Notes:
Summary Clay and plankton particles from natural freshwater samples were collected on glass-fiber filters and stained with toluidine-blue to saturation at pH 8.6. The adsorbed dye was then eluted and quantified by spectrophotometry. The dye-binding capacity per dry weight was a consistent feature of the assemblage of particles contained in each sample, and varied very little between samples obtained from different water sources. This dye-binding assay is far more sensitive than the gravimetric determination of suspended solids.
