Column Adsorption Characteristics of Nitrate Ion by Sodium Carbonate Activated PAN-Based Activated Carbon Fiber
Source abstract
Abstract
It has been confirmed in a previous study that polyacrylonitrile (PAN)-based activated carbon (AC) fiber activated with Na2CO3 adsorbs nitrate ions in batch adsorption. In this study, the activated carbon fiber (ACF) was applied for flow adsorption of nitrate ions using a column. The regeneration capability of the column was also examined. Comparing the amount of nitrate adsorbed by different column diameters, the 7 mm column adsorbed the most nitrate ions. A comparison of the adsorption amount when the nitrate solution was initially adjusted to pH 3 and when the nitrate solution was not adjusted showed that the column without pH adjustment was quickly broken, resulting in a low adsorption amount.
