CELLULOSIC SUPERABSORBENT PRODUCTION WITH CITRIC ACID CROSS-LINKING METHOD

Abstract

In this study, it was aimed to determine water and liquid salt solution absorption capacity of cellulosic superabsorbents that were produced by using citric acid crosslinking method. Cellulosic superabsorbents were prepared with mixing cellulose and carboxymethylcellulose at different ratio. The highest water absorption capacity in water was determined 2616% at pH:7 for cellulosic superabsorbent which was produced with cellulose (10%) and carboxymethylcelulose (90%). Absorption capacity of cellulosic superaborbent in salt solution was calculated 984% for NH4Cl2 liquid salt solution. It was concluded that carboxymethylcellulose had an affirmative effect on water absorption capacity of cellulosic superabsorbents.
