Many natural products have demonstrated functionality as novel, green sorbents for organic compounds.

A magnetic sorbent with stable and superior magnetic behaviour was developed for His-tagged protein purification by immobilized metal affinity chromatography (IMAC). Magnetic, monodisperse and porous silica microspheres 6 mm in size, with bimodal pore size distribution including both mesoporous and macroporous compartments were synthesized as the base material by a staged-shape template hydroly...

Introduction Environmental restriction regarding the quality of transportation fuels and the emissions from them are the most important issues. Because of more stringent regulations and fuel specifications regarding development of better method for deep-desulfurization of fuels are important. There has been recent interest in developing adsorbents for selective desulfurisation by adsorption. Me...

A limited amount and extreme concentration variability of proteomic-related samples require efficient analyte preconcentration and purification prior to the mass spectrometry (MS)-based analysis. Preferably, these steps should be coupled online with chosen fractionation and detection techniques for the minimization of the sample loss. To realize such sample pretreatment, herein, an on-chip soli...

A magnetic solid-phase extraction (MSPE) method based on a novel magnetic sorbent was proposed for the extraction of target compounds from large-volume water samples. First, magnetic hypercrosslinked microspheres (NAND-1) were prepared via membrane emulsification-suspension polymerization and post crosslinking reaction. To ensure that the Fe3O4 nanoparticles could completely pass through the me...

Per- and poly-fluoroalkyl substances (PFAS) are xenobiotics, present at variable concentrations in soils groundwater worldwide. Some of the current remediation techniques being researched or applied for PFAS-impacted involve solidification-stabilisation, soil washing, excavation disposal to landfill, on site situ smouldering, thermal desorption, ball milling incineration. Given large volumes re...

Sorbent material based on a novel thiosemicarbazone compound, C H N S, was prepared by 12 18 4 immobilizing the ligand into gel matrix (SG). The SG sorbent was characterized by FT-IR, EDX, SEM, TEM and TGA. The competitive sorption characteristics of eight transition metal ions (Ag , Cu , Co , Ni , Fe , Pb , Zn + 2+ 2+ + 3+ 2+ 2+ and Mn ) using batch method was studied using atomic absorption s...

Future large-scale production of H2 for use as a clean fuel will likely depend upon gasifying coal or biomass followed by steam reforming the resulting gas mixture and separating the CO2 byproduct. The process of steam reforming and CO2 separation can be greatly simplified by utilizing a new material that combines a reforming catalyst with a sorbent for CO2. Such a material was prepared in the ...
