• •Bi-NH2-BDC is prepared by a simple solvothermal method.•Bi-NH2-BDC has excellent adsorption and photocatalytic properties for DCF.•The adsorption of DCF is due to hydrogen bonding, π-π conjugation and electrostatic interaction.•Bi-NH2-BDC is a reusable and stable photocatalyst. The mass production and widespread use of Pharmaceuticals and Personal Care Products (PPCPs) have posed a serious threat to the water environment and public health. In this work, a green metal-based Metal Organic Framework (MOF) Bi-NH2-BDC was prepared and characterized, and the adsorption characteristics of Bi-NH2-BDC were investigated with typical PPCPs—diclofenac sodium (DCF). It was found that DCF mainly covered the adsorbent surface as a single molecular layer, the adsorption reaction was a spontaneous, entropy-increasing exothermic process and the adsorption mechanisms between Bi-NH2-BDC and DCF were hydrogen bonding, π-π interactions and electrostatic interactions. In addition, Bi-NH2-BDC also had considerable photocatalytic properties, and its application in adsorbent desorption treatment effectively solved the problem of secondary pollution, achieving a green and sustainable adsorption desorption cycle.
