N2 - Antibiotics are tremendously widespread and world widely applied to be discharged in water streams even at quite low concentration, leading to hazard environmental problems, attributing to their high reactivity. The demonstrated work aims to investigate an efficient technology for remarkable photo-degradation of sulfa drugs (sulfamethazine and sulfanilamide) using lanthanide-modified metal organic frameworks (Ln@CA-MIL-68-NH2). Ln@CA-MIL-68-NH2 was investigated to exhibit high efficiency for removal of sulfa drugs via photo-degradation action. MIL-68-NH2 was modified with chloroacetic acid to produce CA-MIL-68-NH2. Afterward, lanthanide (Ln = Tb, Nd, Eu) was successfully impregnated within CA-MIL-68-NH2 to obtain three types of Ln@CA-MIL-68-NH2, abbreviated as Nd@CA-MIL-68-NH2, Eu@CA-MIL-68-NH2, Tb@CA-MIL-68-NH2. The three prepared Ln@CA-MIL-68-NH2 were well characterized via different instrumental analysis. The illustrated data approved the successive immobilization of the as-chosen lanthanides for full filling of the intermolecular spaces and masking of the smooth surface of CA-MIL-68-NH2. The photo-catalytic performance for the prepared Ln@CA-MIL-68-NH2 in ultraviolet light followed the order of Eu@CA-MIL-68-NH2 > Nd@CA-MIL-68-NH2 > Tb@CA-MIL-68-NH2. The photo-catalytic degradation of sulfamethazine and sulfanilamide was significantly enlarged from 62.5 % & 48.8 % using MIL-68-NH2 to 99.8 % and 93.3 % using Eu@CA-MIL-68-NH2, respectively. After modification with Eu, the degradation of sulfa drugs was significantly accelerated, and the degradation rate (k1) was raised from 14.67 to 11.61 min−1 to 48.32 – 43.56 min−1.
