Abstract

''PROCESSO DE ELIMINAçãO DE UM METAL SOLúVEL CONTIDO EM EFLUENTES áCIDOS E/OU BáSICOS PROVENIENTES DE UMA SìNTESE ORGâNICA''. O processo de eliminação de um metal solúvel da invenção compreende as seguintes etapas empregadas continuamente: a) obter efluentes básicos que contenham o metal; b)adicionar um ácido forte aos efluentes básicos até a obtenção de um pH de um valor compreendido entre 0 e 4; c)manter o pH neste valor; d)adicionar um complexante para precipitar o metal monitorando o desenrolar da reação de precipitação e deixar decantar a solução resultante; e e)filtrar a solução para recuperar, por um lado, lamas ácidas contendo o metal precipitado e por outro lado, um filtrado com teor reduzido em metal. Aplicação notadamente ao tratamento de pigmentos à base de ftalocianina.'' PROCESS OF ELIMINATION OF A SOLUBLE METAL CONTAINED IN ACID AND / OR BASIC EFFLUENTS FROM AN ORGANIC SYNTHESIS ''. The process of eliminating a soluble metal of the invention comprises the following steps employed continuously: a) obtaining basic effluents containing the metal; b) add a strong acid to the basic effluents until a pH between 0 and 4 is obtained; c) maintain the pH at this value; d) add a complexant to precipitate the metal, monitoring the progress of the precipitation reaction and let the resulting solution decant; and e) filtering the solution to recover, on the one hand, acid sludge containing the precipitated metal and on the other hand, a filtrate with reduced metal content. Application notably to the treatment of phthalocyanine-based pigments.
