Abstract

método de remoção de impurezas, e , composição. métodos de remoção de impurezas a partir de uma solução de sal orgânico carregado com impurezas através da intermisturação da solução de sal orgânico carregado com impurezas com uma solução de extração, de um modo a formar uma mistura bifásica, em que a intermisturação reduz, de um modo efetivo, a concentração de impurezas no sal orgânico carregado com impurezas, deste modo removendo as impurezas a partir do sal orgânico e formando uma solução de sal orgãnico com um teor de impurezas reduzido e uma fase de solução de extração são aqui providos.
