The adsorption of casein has been studied on a packed column of fine arginineagarose gel. The resience time destributions in this columns was measured by step injection of blue-dextran tracer. The existence of a stagnant-zone causing tailing phenomena was revealed. The equilibrium isotherm for this adsorption system was of the Langmuir form. The theoretical break-through curves were obtained by considering the mixing property and the adsorption-zone model which had been conventionally employed for such a favorable system. The internal and external volumetric mass transfer coefficients were determined by comparring the experimental and theoretical break-through curves. The internal volumetric mass transfer coeffixients, k_Sa_v were about 6×10^<-6>(1/sec) irrespective of the Reynolds number and the external ones, k_fa_v were in agreement with those reported by Kunii and Suzuki.
