In the treatment of a pulp sheet using the aqueous solution containing ferrous sulfate, chlorine contained in the sheet is effectively removed. According to the study of the present inventors, a sheet of bleached pulp obtained using the chlorine-based bleaching agent contains a trace amount of chlorine, and when the chlorine is brought into contact with an aqueous solution containing ferrous sulfate. , Was confirmed to be removed as chlorine gas. Since chlorine is a dioxin-causing substance, it is not preferable to include it in the pulp sheet of the present invention. However, the process of the present invention is very advantageous because it is almost completely removed by the treatment.
