Separation of Cd2+ From Water by Use Of Oxycelluloses And Active Pulp

Popis výsledku v původním jazyce

Natural cellulose and carboxyl celluloses are highly hydrated substances with interesting sorption behaviour. They have the similar chemical composition, but different size of molecules and representation of COOH groups organized into a complex of supramolecular structure. Separation of Cd2+ from polluted water by use of oxycellulose (OC) hydrocolloid fibrous form was compared with dissolved carboxyl methylcellulose (CMC). The carboxyl celluloses adsorption capacity of Cd2+ ions increases with increasing of –COOH group content and distinctly increases with other competitive ions in the aqueous solution. The dissolved and hydrocolloid fibrous forms of carboxyl celluloses were separated from water by use of pulp fibre in both activated and inactivated form as a scavenger. It was revealed that for factual separation efficiency static (i.e. rheosedimentation) or dynamic (i.e. drainage fiber suspension) conditions of the scavenger application evoking counter character of the separation behavior are most important.
