The invention relates to biosorption agents for metal ions with a biological- nature base. Said agents consist of particles which are formed by grinding cereal grains and are insoluble in an aqueous system and/or inorganic solvents, which are modified in such a way that the nitrogen content ranges from 0.1 to 10%, the phosphor content ranges from 0.1 to 20% and the sulfur content ranges from 0.1 to 8%.
L'invention concerne des agents de biosorption pour ions métalliques à base naturelle sur le plan biologique, qui consistent en particules obtenues par mouture de grains de céréales, insolubles en système aqueux et/ou dans des solvants organiques, qui sont modifiés de manière que la teneur en azote soit comprise entre 0,1 et 20 %, la teneur en phosphore, entre 0,1 et 20 % et la teneur en soufre, entre 0,1 et 8 %.
