Cadmium removal using natural zeolite in a circular flume: linear and non-linear analysis

Removal of cadmium using zeolite is investigated in a circular flume. Increasing initial concentration increases the amount of sorbed cadmium but decreases the removal percent of cadmium. Comparing linearization method with non-linear method shows that non-linear method could predict data with lowest sum square of errors. The governing equation for sorption of Cd to zeolite is pseudo 2nd order model. an equation for rate constant estimation, as a function of concentration, is developed
