摘      要：In this work a comparative bioadsorption study between a biocomposite consisting of hydrolysed vineyard pruning waste entrapped in calcium alginate spheres and non entrapped vineyard residue was carried *** have demonstrated that the biocomposite based on lignocellulose-calcium alginate spheres removed 77.3% of dyes,while non entrapped lignocellulose eliminated only removed 27.8% of colour *** experimental data were fitted to several kinetic models（pseudo-first order,pseudo-second order,Chien-Clayton model,intraparticle diffusion model and Bangham model）; being pseudo-second order the kinetic model that better described the adsorption of dyes onto both *** addition,a morphological study（roughness and shape） of alginate-vineyard biocomposite was established under extreme conditions,observing significant differences between hydrated and dehydrated alginate-vineyard *** techniques used to carry out this morphological study consisted of scanning electron microscopy（SEM）,perfilometry and 3D surface analysis.
