The use of the 0.22 mm Millipore cellulose membrane for the measurement of the in-vivo absorption of aquatic particles by the light-transmission method has been explored relative to the performance of the currently used 0.7 mm Whatman GF/F glass-fibre filter. The standard solvent extraction process of pigment removal has been replaced by a newly developed process based on NaClO bleaching. The tests carried out indicate that the 2 filters exhibit comparable performances. It has been shown that a double measurement, performed first on the particles retained in the GF/F filter and then on the sample obtained passing the GF/F filtrate through a Millipore membrane, allows for the selective determination of the absorption of the particle fraction with diameter in the 0.22-0.7 mm range.
