“…However, in the salinity range of 8–35 g L –1 , the adsorption capacity of the protein decreased, possibly because of the electrostatic shielding effect that increased with ionic strength. The shielding effect altered the adsorption of protein by disrupting the π–π conjugation . On the other hand, as salinity increased, the degree of competition adsorption between DON and chloride ions increased, which also impacted the adsorption capacity of DON on porous media.…”

“…The shielding effect altered the adsorption of protein by disrupting the π−π conjugation. 33 On the other hand, as salinity increased, the degree of competition adsorption between DON and chloride ions increased, which also impacted the adsorption capacity of DON on porous media. As a result of excessive salinity, amino acids and urea were more likely to bind to the porous media, immobilizing them and reducing their ability to migrate with water flow.…”

The adsorption of dissolved organic nitrogen (DON) bears the potential to exert a profound influence on the migration ability and groundwater quality. However, the effects of aquifer porous media, characterized by diverse particle dimensions, on the capacity of DON adsorption remain uncertain. The present study clarifies the characteristics and intricate machinations of DON adsorption on porous media with different particle sizes. Our findings suggest that DON adsorption has the potential to achieve immediate equilibrium, and the rate of kinetic adsorption increases as the particle size decreases. Fine sand exhibits a higher adsorption rate (0.030−0.058 kg (mg h) −1 ) and a greater adsorption capacity (137.73−486.67 mg N kg −1 ). Besides, adsorption capacities of amino acids and proteins on porous media are higher, caused by the forces of hydrogen bonding and ester groups. Urea's adsorption capacity exhibits the lowest values, and the main adsorption mechanism is the reactivity of carbonyl groups with porous media. The impact of environmental factors (DOM, metal oxides, and salinity) on adsorption pattern is mainly linked to DON types while being slightly affected by variations in the particle size of porous media. The study highlights that the capacity of DON adsorption on porous media is substantial enough to warrant consideration in site characterization and design of remediation strategies.

Corrodible metals are the newest kind of biodegradable materials and raise a new problem of the corrosion products. However, the removal of the precipitated products has been unclear and even largely ignored in publications. Herein, we find that albumin, an abundant macromolecule in serum enhances the solubility of corrosion products of iron in blood mimetic Hank’s solution significantly. This is universal for other main biodegradable metals such as magnesium, zinc and polyester-coated iron. Albumin also influences corrosion rates in diverse trends in Hank’s solution and normal saline. Based on quantitative study theoretically and experimentally, both the effects on corrosion rates and soluble fractions are interpreted by a unified mechanism, and the key factor leading to different corrosion behaviors in corrosion media is the interference of albumin to the Ca/P passivation layer on the metal surface. This work has illustrated that the interactions between metals and media macromolecules should be taken into consideration in the design of the next-generation metal-based biodegradable medical devices in the formulism of precision medicine. The improved Hank’s solution in presence of albumin and with a higher content of initial calcium salt is suggested to access biodegradable metals potentially for cardiovascular medical devices, where the content of calcium salt is calculated after consideration of chelating of calcium ions by albumin resulting in the physiological concentration of free calcium ions.
