A nitrogen and phosphorus recovery product (NZ-MAP) containing struvite was applied to remove heavy metal ions and lead from water. NZ-MAP was characterized using XRD, FTIR, and SEM/EDS. The effects of dosage, initial pH, and reaction time on the removal process were investigated. The results show that the main component of NZ-MAP is a natural zeolite loaded with struvite. When the dosage is 0.4 g·L, the maximum adsorption amount is 749.74 mg·g, and the adsorption of Pb in the solution increases first and then tends to reach a balance with increase of the pH. Its removal mechanism is mainly Pb (PO) (OH) precipitation, and the effect is best when pH is 5.0. The removal process of Pb from water is more in line with the quasi-two stage kinetic model. In an investigation of the effect of coexisting heavy metal ions on the removal of lead ions in water by NZ-MAP, it was found that coexisting Ni and Cu have little effect on NZ-MAP adsorption on Pb. Coexisting Zn and Al obviously inhibit the adsorption of Pb by NZ-MAP. The research shows that NZ-MAP material can remove lead ions from water efficiently, thus offering an effective method for doing this.

Lead (Pb) is a highly toxic heavy metal that causes significant health hazards and environmental damage. Thus, the detection and removal of Pb ions in freshwater sources are imperative for safeguarding public health and the environment. Moreover, the transformation of single resources into multiple high-value products is vital for achieving sustainable development goals (SDGs).

Poly(ethylene oxide) (PEO)-based solid-state polymer electrolyte (SPE) is a promising candidate for the next generation of safer lithium-metal batteries. However, the serious side reaction between PEO and lithium metal and the uneven deposition of lithium ions lead to the growth of lithium dendrites and the rapid decline of battery cycle life. Building a LiF-rich solid electrolyte interface (SEI) layer is considered to be an effective means to solve the above problems.

Currently, lithium-ion batteries (LIBs) are at the forefront of energy storage technologies. Silicon-based anodes, with their high capacity and low cost, present a promising alternative to traditional graphite anodes in LIBs, offering the potential for substantial improvements in energy density. However, the significant volumetric changes that silicon-based anodes undergo during charge and discharge cycles can lead to structural degradation.

Hole-transport layers (HTL) in perovskite solar cells (PSCs) with an n-i-p structure are commonly doped by bis(trifluoromethane)sulfonimide (TFSI) salts to enhance hole conduction. While lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) dopant is a widely used and effective dopant, it has significant limitations, including the need for additional solvents and additives, environmental sensitivity, unintended oxidation, and dopant migration, which can lead to lower stability of PSCs. A novel ionic liquid, 1-(2-methoxyethyl)-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)amide (MMPyTFSI), is explored as an alternative dopant for 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamino)-9,9'-spirobifluorene (spiro-OMeTAD).

A novel silica-based material (SBM), synthesized from chemically-, thermally-, and mechanically-treated blast furnace slag (TBFS), was examined for its batch-mode lead adsorption capacity based on various parameters. Physicochemical examinations revealed that the formulation of the new SBM consisted mainly of silica, which represented 81.79% of its total composition.
