Mesoporous Zr-G-C3N4 Sorbent as an Exceptional Cu (II) Ion Adsorbent in Aquatic Solution: Equilibrium, Kinetics, and Mechanisms Study

A mesoporous Zr-G-C3N4 nanomaterial was synthesized by a succinct-step ultrasonication technique and used for Cu2+ ion uptake in the aqueous phase. The adsorption of examined varying operating parameters, including initial metal concentration, contact time, pH value. nanosorbent displays graphitic carbon nitride (g-C3N4) ZrO2 peaks with crystalline size ~14 nm, as determined XRD analysis. sorbent demonstrated BET-specific surface area 95.685 m2/g pore volume 2.16 × 10−7 m3·g−1. Batch mode tests revealed that removing Cu (II) ions pH-dependent, maximal removal achieved at = 5. adsorptive process is well described Langmuir isotherm pseudo-second-order kinetics model. maximum capacity nanocomposite to be 2.262 mol·kg−1 time 48 min. results confirmed fabricated effective regenerable could potent adsorbent heavy metals from systems.
