“…Wang et al 16 obtained uranyl-specific nanofluidic channels by supporting the layer spacing of graphene sheets to twice the ionic length of UO 2 2+ through a phenyl unit covalent column, thus achieving efficient and rapid extraction of uranyl ions. Hu et al 35 reported the study of size exclusion effect in overcoming the interference of natural organic matter (NOM) on antibiotic adsorption. By precisely tuning the pore size of organic mesoporous carbons (OMCs), high rejection of NOM and high adsorption rate of antibiotics were achieved.…”

“…In addition, no relationship between retention factor and molecular weight can be found, which indicates that the retention factor is determined by the interaction between the analytes and the stationary phase, ruling out the size exclusion effect. 21 Moreover, the relationship between chemical property log P and log k is investigated (Fig. 3b).…”

Production of liquid fertilizers containing nitrogenous nutrients and biostimulants from sewage sludge (SS-NB) has been attracting increasing attention due to its excellent fertilization effect and resource recycling attributes. To better understand the functional effects of nutrients and biostimulants in SS-NB on soil, the adsorption capacity and mechanism of straw biochar (SB) and wood chip biochar (WCB) for alkaline and neutral SS-NB components were investigated. The adsorption of total organic carbon (TOC) from alkaline and neutral SS-NB by WCB was 61.14% and 89.73%, respectively, higher than that by SB, which was 56.25% and 83.36%. Moreover, TOC from neutral SS-NB was more readily adsorbed, especially for fulvic and humic acids. SB had a strong adsorption capacity for calcium ions and nitrogen (TKN, nitrate N, protein, amino acid) and released large amounts of P. In addition, WCB and SB showed a strong affinity for macromolecules (proteins) and reducing substances (lignin and lipids) and excellent fixation ability for phytohormones and allelochemicals. However, WCB adsorbed more types of molecular substances than SB while maintaining a high immobilization rate. Analysis of the adsorption mechanism showed that surface amino groups of the biochar were involved in adsorption, while WCB had additionally high adsorption efficiencies through pore adsorption, hydrogen bonding adsorption and pore size-exclusion effects. The study revealed that biochar can be used as an efficient adsorption carrier for SS-NB to improve soil fertility management. Graphical Abstract
