Kenaf is a widely
cultivated crop, particularly in the tropics. Kenaf core fiber (KCF) is a
natural cellulose fiber derived from the plant and it is an important raw
material for a variety of products. An attempt was made to chemically
quaternized KCF (QKCF) as an adsorbent to increase adsorption affinity towards
anionic reactive red-RB dye (RR). KCF was quaternized by treating with (3-chloro-2-hydroxypropyl)
trimethylammonium chloride under basic condition. The efficiency of QKCF was
investigated by adsorption studies for removing anionic RR dye from aqueous
solutions. All experiments were conducted at a batch system and influential
parameters cover pH, adsorbent dose, initial dye concentration, agitation
speed, temperature, and contact time were investigated. Studies showed that
removal efficiency of RR dye increases with increasing the adsorbent dose, agitation speed, temperature, and
contact time. The equilibrium data were best represented by the Langmuir
isotherm model with maximum adsorption capacity of 169.5 mg/g, and the kinetic
data were found to follow the pseudo-second-order kinetic model. In general,
QKCF could be suggested as an efficient and low-cost
adsorbent for removal anionic dyes.
