Abstract:
(EN) The invention relates to biosoprtion agents for metal ions with a biological-natural 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 %.
(FR) 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 %.
(DE) Die Erfindung betrifft Biosorbentien für Metallionen auf biologisch-natürlicher Basis, wobei diese aus durch Mahlung von Getreidekörnern gebildeten, im wäßrigen System und/oder in organischen Lösungsmitteln unlöslichen Partikeln bestehen, die so modifiziert sind, daß der Stickstoffgehalt im Bereich von 0,1 bis 20 %, der Phosphorgehalt im Bereich von 0,1 bis 20 % und der Schwefelgehalt im Bereich von 0,1 bis 8 % liegt.
