Many metal-organic frameworks are water labile, including the iconic Hong-Kong University of Science and Technology-1 (HKUST-1). Spray-dry encapsulation of HKUST-1 crystals into polystyrene microspheres is reported here to yield composites that are resistant to water but retain most of the excellent gas sorption capacity of HKUST-1. These composites are demonstrated to exhibit superior water ad...

Viruses as well as other (bio-)colloids possess a pH-dependent surface charge in polar media such as water. This electrostatic charge determines the mobility of the soft particle in an electric field and thus governs its colloidal behaviour which plays a major role in virus sorption processes. The pH value at which the net surface charge switches its sign is referred to as the isoelectric point...

The abundantly available bio waste, crab shell powder was used as an adsorbent for the removal of pollutants like Congo Red. The morphological, textural and chemical characterization of the biomass was done with SEM, XRD, EDS and FT-IR studies. The nature and mechanism of the process were determined from equilibrium, kinetic and thermodynamic studies. The results exhibited that the bio waste su...

IRMOF-3 nano/microcrystals with controllable morphologies and sizes were successfully obtained by a simple solvothermal method. The shape evolution of IRMOF-3 crystals from cube to truncated cube, cuboctahedron, truncated octahedron and finally to octahedron was achieved by adjusting the amount of surfactant. The surfaces of the IRMOF-3 nano/microstructures are affected by the reaction temperat...

Increasing interest is being envisaged by environmental researchers in controlling the phosphates pollution in natural waters by evoking the surface sorption characteristics of bio-waste materials of flora origin. In the present work, a thorough investigation has been made to find powders of leaves or their ashes of different classes of plants, having the affinity towards phosphate ions. 10 pla...

In this study, the DNA sorption performance of diatomite-Zn(II) embedded supermacroporous monolithic p(HEMA) cryogels were investigated for the purpose of designing a novel adsorbent that can be utilized for DNA purification, separation and immunoadsorption studies such as removal of anti-dsDNA antibodies from systemic lupus erythematosus (SLE) patient plasma. Poly(2-hydroxyethyl methacrylate) ...

The study was carried to evaluate the ability of defatted seed Adansonia digitata (DFSE) remove methylene blue dye from contaminated water. optimum parameters such as contact time, particle size, absorbent dose, initial concentration, and pH were investigated by performing batch experiments models. kinetics isotherms adsorption evaluated varying concentration using parameters. time is 90 min re...
