abstract = "As tighter regulations on colour in discharges to
water bodies are more widely implemented worldwide, the
demand for reliable inexpensive technologies for dye
removal grows. In this study, the removal of the basic
dye, methylene blue, by adsorption onto low-cost sodium
alginate-kaolin beads was investigated to determine the
effect of operating parameters (initial dye
concentration, contact time, pH, adsorbent dosage,
temperature, agitation speed) on dye removal
efficiency. The composite beads and individual
components were characterized by a number of analytical
techniques. Three models were developed to describe the
adsorption as a function of the operating parameters
using regression analysis, and two powerful intelligent
modeling techniques, genetic programming and artificial
neural network (ANN). The ANN model is best in
predicting dye removal efficiency with R2 = 0.97 and
RMSE = 3.59. The developed model can be used as a
useful tool to optimize treatment processes using the
promising adsorbent, to eliminate basic dyes from
aqueous solutions. Adsorption followed a pseudo-second
order kinetics and was best described by the Freundlich
isotherm. Encapsulating the kaolin powder in sodium
alginate resulted in removal efficiency of 99.56percent
and a maximum adsorption capacity of 188.7 mg.g-1, a
more than fourfold increase over kaolin alone",
