Modeling Of Cane Sugar Colorant Removal In Packed-Bed Ion Exchange Columns And An Investigation Into Pretreatment Methods, Bruce Malcolm Ellis

LSU Master's Theses

Cane sugar colorants have been extensively researched but still little is known about their exact compositions. Rather than distinct compounds, they are a mixture of many compounds. Some it is assumed can be classified into the pseudo components that have been defined using gel permeation chromatography, based on molecular weight. The defining of these components has allowed the colorants to be modeled independently, instead of as one lumped color parameter. The measured colored components were modeled using a linear driving force adsorption model, which could be applied in the design process for optimizing the decolorizing capacity of the resins. The …
