The invention relates to a process for reducing bossting time for formation of aluminum electorlytic capacitance anode foil, comprising boiling with pure water, forming, depolarizing and reforming. There is a pretreatment before boiling with pure water: putting corrosive foil into nitrate liquid for 1-60 seconds at room temperature, the proportion by weight of nitrate liquid is 1% -15%. The invention keeps the initial range of the product CV of specific capacitance and withstand voltage, and reduces the bossting time for aluminum electorlytic capacitance anode foil, which can meet the specific requirement for raw material of anode foil, and it is suitable for high and low pressure aluminum electrolytic capacitance.
