A novel spouted bed reactor is evaluated for water treatment by an adsorption and electrochemical regeneration process. The adsorbent is a bisulphate graphite intercalation compound with low specific surface area but high electrical conductivity, suitable for adsorption of contaminants and simultaneous electrochemical regeneration within a single unit. The effects of current density and liquid flow rate on Acid Violet 17 removal were investigated. The hydrodynamic behavior of the liquid spouted bed reactor was characterized by a flow regime map. A four-parameter model has been developed to describe the adsorption and electrochemical regeneration process in the liquid spouted bed reactor. It was found that the experimental data of dye removal agrees well with the modelled simulations.

Growth hormone (GH) is a peptide containing 191 amino acids that is secreted by the acidophilic cells of the pituitary and has a very important action on growth during infancy and adolescence (Devesa et al 1996). To perform this action GH needs the collaboration of a full series of factors such as, thyroid hormones and sexual hormones together with an appropriate nutrition., Pres. Human Factors and Medicine Panel (HFM) Symposium, Toulon, France, 11-14 Oct 1999, p23-1/23-5.
