摘要
Brine is a solution of salt （usually sodium chloride） in water. In different contexts, brine may refer to salt solutions ranging from about 3.5% （a typical concentration of seawater, or the lower end of solutions used for brining foods） up to about 26% （a typical saturated solution, depending on temperature）. Adsorption onto activated carbon is the most widespread technology for the removal of pollutants from water and wastewaters. In this study, continuous fixed-bed-column systems were investigated. The adsorbents which authors use are： spruce （Picea abies） untreated, spruce modified by autohydrolysis. The column systems were filed with biomass at various initial dye concentrations, flow rates and bed-depths. The column kinetics of MB （Methylene Blue） adsorption on spruce （Picea abies） untreated, spruce modified by autohydrolysis was simulated. Economies arise when the facility that can use such adsorption materials is near a source of a lignocellulosic waste as agricultural residues, thus saving transportation cost and contributing to industrial ecology at local level.
