Abstract

Un procedimiento para la separación de metales pesados y halógeno de material de desecho obtenido de la incineración de material de PVC o un residuo obtenido de un procedimiento de reciclado de PVC que contiene una mezcla de estos materiales, comprendiendo dicho procedimiento para la separación las etapas de: i) extraer selectivamente el halógeno del material de desecho a un valor de pH entre 7 y 11, para obtener un material de desecho (A) que contiene metal pesado y un líquido (B) que contiene halógeno; i¿) si es necesario, repetir la etapa i) hasta proporcionar un material de desecho (A¿) esencialmente exento de halógeno; ii) extraer selectivamente el metal pesado del material de desecho (A) o (A¿) de la etapa i) o i¿), a un valor de pH entre 0 y 4; ii¿) si es necesario, repetir opcionalmente la etapa ii) hasta proporcionar un material de desecho esencialmente exento de metal pesado y halógeno; iii) precipitar opcionalmente el metal o metales extraídos de las etapas ii) o ii¿).
