In this study, Mg and/or Al modified biochars (MABC, MBC, ABC) prepared by co-precipitation were to explore their phosphate adsorption capacity from aqueous solution and the potential for soil phosphate interception. The results revealed that MABC composites contained more functional groups than MBC and showed a higher surface area than ABC. The surface of MABC contained dispersed MgAlO, Mg(OH), AlOOH and AlO crystals that were associated with its enhanced maximum phosphate adsorption capacity (153.40 mg g). According to Langmuir model, the maximum adsorption capacity of MABC was 15.91, 1.85, and 93.54 times the capacity of MBC, ABC, and raw biochar (BC), respectively. The addition of MABC in red soil could significantly slow down the release of soil phosphorus, and MABC also had a stronger phosphate interception capacity (59.89%) than other BCs. In summary, MABC exhibits superior phosphate adsorption and interception capacity, making it ideal for treatment and prevention of phosphorus-polluted water.

Although the use of biochar as an adsorbent for the removal of various pollutants from wastewater is well established, the use of biochar/modified biochar for the scavenging of antibiotics from aqueous media in the Fenton-like system receives less attention. The highest kasugamycin (KSM) adsorption capacity (5.0 mg g) was obtained from the pristine biochar at the lowest initial pH of 3 in Fenton-like system.

In the current research mushroom/bentonite clay (RDBNC) as a low-cost bionanosorbent was investigated for adsorption of methylene blue (MB) and malachite green (MG) dye from contaminated water. The bionanosorbent was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), Scanning electron microscopy (FESEM), Thermal Gravimetric Analysis (TGA), and Zeta-potential techniques. Adsorption experiments of RDBNC for MB, MG dyes following Freundlich isotherm and pseudo second order kinetic models.

Exploiting supramolecular secondary building units (SSBUs) for developing porous crystalline materials represents an exciting breakthrough that extends the boundaries of reticular chemistry. However, shaping polynuclear clusters sustained by non-covalent interactions for the assembly of hydrogen-bonded frameworks remains a critical challenge. This study presents a novel strategy to stabilize SSBUs by tuning the π-stacking geometry of conjugated building blocks, facilitating the creation of hydrogen-bonded frameworks with tailored architectures for demanding gas separation.
