Study on the extraction of the caramel pigment from the yam diosgenin processing waste water

Le résumé fourni par la source

Yam diosgenin processing waste water has the characteristics of high concentration, high colority and low pH value. The best material for removing the caramel pigment from the waste water of yam saponin was powder active carbon through the comparation among the absorbing resin, ion exchange resin and active carbon. The optimal adsorption conditions by the active carbon were obtained by means of orthogonal experiment: temperature 40 ℃, absorbing time 45 min, amount of active carbon 8% and the pigment removal rate up to 98.75%, the solid content removal rate up to 72.97%.
