description The invention belongs to the field of textile printing and dyeing, and relates to a mild and safe pH buffer system with high color light stability and a preparation method and application thereof, the pH buffer system comprises a regulator A, a regulator B, a complexing agent, a penetrant, silicon modified graphene oxide and a silicon-containing dispersant; the regulator A is at least one of malic acid, citric acid, acetic acid and ammonium sulfate, the regulator B is composed of organic acid, and the organic acid is carboxylic acid or sulfonic acid. By limiting the specific weight ratio of the regulator A to the regulator B, the regulator A, the regulator B, the silicon-modified graphene oxide and the silicon-containing dispersant play a synergistic effect to obtain a pH buffer system, the pH buffer system is applied to dyeing and has excellent pH value buffer performance, and the pH value of a working solution before and after dyeing is stable; dyed color light is good in brilliance and excellent in reprodu
