Title (EN) A METHOD OF PRODUCING BISMUTH VANADATE AND RELATED PRODUCTS
(FR) MÉTHODE DE PRODUCTION DE VANADATE DE BISMUTH ET PRODUITS ASSOCIÉS
Abstract:
(EN) There is provided a method of producing bismuth vanadate, the method comprising preparing a mixture having a pH of no more than 3.0 by adding a leaching solution containing vanadate ions to a bismuth salt solution, the leaching solution being derived from a vanadium source, and precipitating bismuth vanadate from the mixture. In particular, said vanadium source is an oil refinery waste or carbon black waste. Also provided are bismuth vanadates obtained therefrom.
(FR) L'invention concerne une méthode de production de vanadate de bismuth, la méthode comprenant la préparation d'un mélange ayant un pH inférieur ou égal à 3,0 par ajout d'une solution de lixiviation contenant des ions vanadate à une solution de sel de bismuth, la solution de lixiviation étant dérivée d'une source de vanadium, et la précipitation du vanadate de bismuth à partir du mélange. En particulier, ladite source de vanadium est un déchet de raffinerie de pétrole ou un déchet de noir de carbone. L'invention concerne également des vanadates de bismuth ainsi obtenus.
