Investigation of the Influence of Conditions of Reprecipitation of Cellulose on its Adsorption Properties

Resumo

The reprecipitation of cellulose from alkaline solutions was studied. The influence of the following factors on cellulose specific surface area was investigated: temperature, precipitant concentration, cellulose concentration in a stock alkaline solution, rate of precipitation, and presence of polyethylene glycol. After considering the results of regression analysis, the effects of different parameters on cellulose specific surface area were determined. The ratio of crystalline and amorphous phases in cellulose before and after reprecipitation was determined by XRD analysis.
