Mercury is one of the most toxic heavy metals. Various techniques have been used to remove it from water sources. Among these, adsorption a low-cost and effective method mercury even in very low concentrations. One adsorbents that has gained considerable popularity recently zeolite imidazolate framework-8 (ZIF-8). In this study, after synthesis ZIF-8, its properties were determined using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission electron microscopy (FESEM). Temperature (25–61 °C), contact time (5–85 min), adsorbent dosage (0.1–0.9 g/L), pH (2–10), initial concentration (24- mg/L) investigated. The optimal conditions for response surface methodology (RSM). elimination included primary 4 mg/L, temperature 61°C, dose (0.5 7; efficiency under these was 91.66%. equilibrium data analysed Langmuir Freundlich isotherm models, model found be consistent with (R2 = 0.9363). kinetics closely matched pseudo-second-order 0.9998). These results indicate nanoporous ZIF-8 can successfully eliminate aqueous environments.

In the present work, sol-gel and co-precipitation techniques were used for synthesis of Fe-TiO2@Fe3O4 nanoparticles (NPs) Fe3O4, respectively. These photocatalytic removal amoxicillin. characteristics analyzed via Energy Dispersive X-ray Spectroscopy) EDX(, field emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy) FT-IR(, Vibrating Sample Magnetometer) VSM(, diffraction) XRD(, Brunauer Emmett Teller (BET), Diffuse reflectance spectroscopy (DRS). The effect different parameters, like pH (11-3), number NPs (100–200 mg), amoxicillin primary concentration (40–80 mg/L), on elimination by OFAT method (one factor at a time) diverse times (0–75 min), was studied. mean size Fe-TiO2 Fe3O4 is 15.05 18.12 nm, incorporation iron into titanium dioxide acts as an intermediate energy level, reducing band gap shifting light absorption to visible range. Chemical bonding stretching vibrations related hydroxyl group (structural water OH group) observed in FT-IR results. optimum results maximum effectiveness reaction rate constant achieved 7. weight 600 mg 40 mg/L 75 min time. decreased from 99.9% 89% after five recycling steps.
