Title
(EN) METHOD FOR REMOVING PESTICIDES AND/OR PHYTODRUGS FROM LIQUIDS USING CELLULOSE, CHITOSAN AND PECTOLIGNINCELLULOSIC MATERIAL DERIVATIVES
(FR) PROCEDE POUR ELIMINER LES PESTICIDES ET/OU LES PRODUITS PHYTOSANITAIRES CONTENUS DANS DES LIQUIDES, A L'AIDE DE DERIVES DE CELLULOSE, DE CHITOSANE ET DE MATIERES PECTOLIGNINOCELLULOSIQUES
Abstract
(EN)
The method for removing pesticides and/or phytodrugs from alimentary liquids, from drinkable and superficial waters and from waste waters includes that such liquids are treated with chitin, or with alkyl and aryl derivative of cellulose, of hemicellulose, of chitin, of chitosan, of pectin and of pectolignincellulosic materials. After treatment with such powdery adsorbents for a time period until 24 hours at a concentration ranging between 10 and 4000 grams for hectoliter of treated liquid, and at temperatures up to 60 °C, the adsorbent is separated from the liquid getting the removal of the phytodrugs and/or pesticide up to 100 % of their initial value.
(FR)
Ce procédé, qui sert à éliminer les pesticides et/ou les produits phytosanitaires contenus dans des aliments liquides, dans des eaux potables et de surface et dans des eaux usées, consiste à traiter ces liquides avec de la chitine ou avec un dérivé alkyle ou aryle de cellulose, d'hémicellulose de chitine, de chitosane, de pectine et de matières pectoligninocellulosiques. Après traitement avec ces agents adsorbants sous forme pulvérulente pendant une période de 24 heures au maximum à des concentrations comprises entre 10 et 4000 grammes par hectolitre de liquide traité, et à des températures allant jusqu'à 60 °C, l'agent adsorbant est séparé du liquide, ce qui permet d'obtenir l'élimination d'une proportion de produits phytosanitaires et/ou pesticides allant jusqu'à 100 % de leur valeur initiale.
