Background: Hydrophilic Interaction Liquid Chromatography (HILIC) is an outstanding strategy for the challenging analysis of hydrophilic and polar components. Nevertheless, analysis under HILIC mode typically consumes 70%-95 % acetonitrile with the disadvantage of high analytical costs, being environmentally unfriendly and causing biohazards, which is not in line with the concept of green chromatography. Research has shown that Per Aqueous Liquid Chromatography (PALC) simultaneously emphasizes efficient analytical performance for hydrophilic analytes and green analytical concepts.

- The study created graphene-like biochar (IZBC) from wheat straw using pyrolysis, identifying three key stages in graphene formation: shell core generation, carburization, and carbon precipitation, highlighting different graphene yield percentages at varying temperatures.
- At temperatures between 500-900 ℃, the highest graphene production was observed at 800-900 ℃ (38%), with iron chloride (FeCl) being the most effective catalyst contributing to 64% of the total graphene.
- IZBC demonstrated a high adsorption capacity for dimethoate (980 μmol/g) through mechanisms like pore filling and electrostatic attraction, although this process was negatively affected by the presence of other ions and humic acid, and
Periodic mesoporous organosilicas (PMO) hydrophilic microspheres were synthesized by co-condensation of sulfated polysaccharide from Lilum lancifolium Thunb. bridged silane (SLLTPBS) and polyhedral oligomeric silsesquioxane (POSS) as stationary phase (PMO(SLLTP-POSS)) for per aqueous liquid chromatography (PALC), which would overcome the disadvantages of using a large amount of acetonitrile on the hydrophilic interaction liquid chromatography (HILIC) columns. Average particle size of PMO (SLLTP-POSS) microspheres was 4.
