According to the brightener suitable for the acid electroplating copper liquid and the preparation method of the brightener, the brightener is of a disulfide sodium disulfonate structure, it can be guaranteed that soluble anode copper balls obtain extremely thin film layers while high depth capacity is obtained, accumulation of the anode film layers in an anode bag is slowed down, and the service life of the anode bag is prolonged. Compared with the prior art, the cleaning frequency of the anode copper ball is reduced, the loss of the copper ball is reduced, the material cost is saved, the cleaning frequency is reduced, the investment of human resources is reduced, the smooth production is ensured, the pollution of the bath solution is reduced, and the replacement frequency of the bath solution is reduced. By introducing a carbon chain structure of oxygen atoms into molecules, the surface reaction activity of the molecules of the brightener on soluble anode copper balls is reduced while the water solubility o
