Abstract Three varieties of nicotinic acid root-typehydrotalcite (LDHs-VB3) were prepared by roasting hydration reconstruction method, employing natural magnesium-aluminium hydrotalcite as the source and nicotinic acid as the modifier. The effects of solution pH on the crystalline structure, functional groups and microscopic morphology of LDHs-VB3(pH=9.3), LDHs-VB3(pH=10.3) and LDHs-VB3(pH=11.3) were analyzed. Furthermore, the specific surface area, pore size distribution and chloride ion adsorption properties of these three LDHs-VB3 samples were investigated. The findings revealed that nicotinic acid anions (VB3^-) are not successfully intercalated into the LDH interlayer at a pH of 11.3, whereas significant intercalation is achieved at pH values of 9.3 and 10.3. Among the three samples, LDHs-VB3(pH=9.3) exhibits the largest interlayer spacing, measuring 15.32 . In contrast, LDHs-VB3(pH=10.3) demonstrates the highest specific surface area and optimal crystallization. Besides, all the samples’ adsorption processes follow the Langmuir isothermal adsorption model, and the maximum chloride adsorption of LDHs-VB3(pH=9.3), LDHs-VB3(pH=10.3) and LDHs-VB3(pH=11.3) are 23.847 mg/g, 39.128 mg/g and 29.200 mg/g, respectively. In addition, LDHs-VB3(pH=9.3) and LDHs-VB3(pH=10.3) adsorb chloride ions mainly by both ion exchange and surface adsorption, while LDHs-VB3(pH=11.3) primarily relies on surface adsorption. Although the Cl^- adsorption capacities of these three LDHs-VB3 samples are all lower than that of CLDHs, LDHs-VB3(pH=9.3) and LDHs-VB3(pH=10.3) possess the dual roles of releasing VB3^- and adsorbing Cl^- and exhibit good thermal stability, making them potential candidates as corrosion inhibitors for reinforcement bars in reinforced concrete. These findings provide a reference for the design and green development of the LDHs-type corrosion inhibitors.
