Abstract:
1. A manufacturing method for an anion adsorbing carbonized plant material, comprising: providing a ligneous plant material with conductive tissue cut into sizes not greater than 50 mm; soaking and stirring the ligneous plant material in a liquid solution having 0.1 weight % to 7.0 weight % of a calcium chloride with individual diameter sizes not greater than 100 nm for a time period to introduce the calcium chloride into the conductive tissue of the ligneous plant material; removing the soaked ligneous plant material with the calcium chloride positioned within the conductive tissue; drying the soaked ligneous plant material; carbonizing the dried ligneous plant material with the calcium chloride in the conductive tissue at a temperature of 650° C. to 750° C. for a time period to enable carbonization of the dried ligneous plant material, with deposits of calcium chloride within 2 weight % to 25 weight % of the carbonized plant material; and applying a hydrochloric acid solution to the carbonized plant material to react with the calcium chloride, within a pressure range of 1330 Pa to 13.3 Pa, to remove extra crystals of CaCl
