Boron is one of the significant micronutrients for the plants; however, its excessive concentrations are lethal to plants. The accumulation of boron may cause damage to the liver, kidney, nervous system, respiratory system, digestive system, reproductive system and even threaten human life. Researchers consider using different methods to prepare boron chelating resins. In this work, two innovative, facile, and low‐cost methods were developed to prepare polystyrene-alcohol resins. The KDN and KLA resins had the highest adsorption capacity for boric acid in an aqueous solution at 288 K ,and the adsorption capacity was 36.17 mg·g-1 and 43.47 mg·g-1, respectively. The desorption percentages of boric acid on KDN and KLA resins were 90.75 % and 90.32 % respectively, by using 1 mol·L-1 HCl as an eluent. Therefore, KDN and KLA resins have the characteristics of a simple experimental process, large adsorption capacity, high elution rate, reusable, and low production cost. Therefore, it has a high commercial value and development prospects.
