【摘要】 针对制备富铬酵母所需培养基的需要,采用湿热-酸法处理含铬废革料,使之发生适度的降解。首先在水蒸汽的作用下使含铬废革料发生初步降解,再进行酸法二次降解。实验结果表明,含铬废革料经湿热-酸法降解处理后所得降解液的铬质量浓度基本稳定,能够满足利用含铬废革料制备富铬酵母的需要。更多还原

【Abstract】 A twostep method, namely hydrothermalacid method, was applied in the degradation of chromiumcontaining leather waste, in which water vapor and hydrochloric acid were used, respectively. The results showed that the hydrothermalacid method could meet the need of preparation of chromiumenriched brewer’s yeast from chromiumcontaining leather waste. 更多还原
