Procedure

In this process, as can be seen from reaction formula 4, some sodium carbonate is consumed by reacting with the PCB to form NaCl. Moreover, as shown by reaction formula 5, some sodium carbonate is converted into sodium bicarbonate by reaction with the resulting carbon dioxide. Furthermore, as shown by reaction formula 6, the carbon dioxide existing in excess is used to form an aqueous solution of sodium bicarbonate and carbonic acid. Thus, the sodium carbonate particles were exhausted and, therefore, the PCB decomposition reaction is retarded to an extreme degree.
