Abstract/Summary:
An enzyme-assisted flotation deinking process was developed using ;The effects of the ;A pulp pretreatment with an ;An ;Pulp pretreatment with cellulases and ;The degradation velocity of cationic starch decreased with increasing degree of substitution. The same trend was found for hydroxyalkylated starches. An increasing degree of oxidation resulted in an increase in degradation velocity.
