摘要： Le procédé décrit sert à purifier des solutions contenant des métaux, tels que notamment mais non exclusivement des eaux résiduaires qui contiennent des métaux tels que du mercure, du cadmium et/ou du plomb, dans lesquelles les métaux en question sont présents sous forme hydrosoluble, par exemple sous la forme d'un complexe de chlorures. Ledit procédé consiste à faire passer la solution à travers un matériau d'échange ionique (4) qui se compose essentiellement de cellulose sulfhydratée, dans laquelle sont absorbés les métaux; à régénérer le matériau d'échange ionique (4) après l'adsorption d'une quantité prédéterminée de métal par rinçage du matériau d'échange ionique avec une solution aqueuse qui contient de l'acide chlorhydrique (HCl) selon une concentration d'au moins 1 mole HCl; et à soumettre les métaux en question sous forme de sulfure à une précipitation selon un procédé connu à partir du liquide qui est élué du matériau d'échange ionique (4) dans le procédé de rinçage mentionné ci-dessus. La présente invention se rapporte également à un appareil de mise en oeuvre dudit procédé.

摘要： A process for preparing a carboxylated cellulose ion-exchange material comprises heating a mixture of cellulose and citric, isocitric or aconitic acid at 100-160° C while continuously removing water, and then treating the product with aqueous alkali at a pH of 8 to 11 to hydrolyse cross-linked acid residues. Carboxylated cellulose ion-exchange materials having an ion-exchange capacity towards cupric ions of 1.5 to 3.5 milliequivalents per gram and their use in removing heavy-metal ions from aqueous solutions are claimed. Citrated sawdust is a preferred product useful in industrial effluent treatment and precious metal recovery.

摘要： The invention relates to a rapid-action agent for preparing cold and hot beverages from drinking water, in particular coffee or tea. Taking into consideration the disadvantages of known prior art, the aim of the invention is to provide a rapid-action agent for preparing cold and hot beverages from drinking water, said agent being easy to use, having a uniform, consistent action, eliminating the risk of microbial formation and noticeably improving the taste of the beverage after a relatively short treatment time. To achieve this, the inventive agent consists of cellulose fibres, which are modified by a chemical reaction, forming phosphate ester groups and which have an ion-exchange capacity of at least 50 mg copper per g dried fibres, said agent being brought into contact, at least temporarily for a period of several minutes, with the drinking or infusion water by immersion. The cellulose fibres are chemically modified by phosphorylation using phosphoric acid or ammonium phosphate, until a phosphor content of between 3 and 8 mass % has been obtained. To increase the mechanical stability of the fibres, the phosphorylation can also be combined with a urea treatment, until a nitrogen content in the form of carbamide groups of at least 1 mass % is obtained. The modified cellulose fibres have such a rapid-action that after immersion in the water of the preparation, a noticeable improvement in the taste of the drinking water and the beverages prepared from said water is achieved after only a few minutes, optionally aided by a light stirring of the liquid, without adversely affecting the taste of the respective beverage.
