- Methylene blue adsorption onto modified lignin from sugar cane bagasse N. Consolin Filho E. C. Venancio M. F. Barriquello A. A. W. Hechenleitner E. A. G. Pineda Química lignin adsorption methylene blue The adsorption kinetics and equilibrium of methylene blue (MB) onto reticulated formiclignin (RFL) from sugar cane bagasse was studied. The adsorption process is pH, temperature and ionicstrength (μ) dependent and obeys the Langmuir model. Conditions for higher adsorption rate andcapacity were determined. The faster adsorption (12 hours) and higher adsorption capacity (34.20mg.g-1) were observed at pH = 5.8 (acetic acid-sodium acetate aqueous buffer), 50 °C and 0.1 ionicstrength. Under temperature (50 °C) control and occasional mechanical stirring it took from 1 to 10days to reach the equilibrium. 2007 artículo científico 0100-4670 https://www.redalyc.org/articulo.oa?id=42932409 en http://www.redalyc.org/revista.oa?id=429 Eclética Química application/pdf Universidade Estadual Paulista Júlio de Mesquita Filho Eclética Química (Brasil) Num.4 Vol.32
