Blast furnace slag (BFS) is a secondary material generated during the process of producing iron in blast furnaces, prompting scholars to concentrate on its efficient management and broad application for creation valuable commodities. This study examines mineral composition, adsorption characteristics, utilization BFS silica counterparts. Recent developments functionalized materials pollution mitigation are examined, specifically concentrating elimination nitrogen, phosphorus, metal ions, pharmaceutical effluents, waste oils, dye molecules from wastewater. Moreover, these inexpensive adsorbents exhibit significant specific surface areas, possess microporous configurations, contain alkaline components like calcium oxide, magnesium aluminum oxide. review further elucidates present state BFS-based absorption acid gases, with focus CO₂. The problems associated widespread usage analyzed, potential solutions effective resource discussed.

To counter the threat to wellbore stability in shale formations posed by filtrate invasion and pressure transmission of oil-based drilling fluids (OBDFs), it is critical develop a material that can effectively seal micron-scale fractures. Graphene oxide was surface-modified cross-linking entanglement strategy used prepare tough carbon aerogels (HPGA2) with porous structure, HPGA2 were characterized Fourier transform infrared, Raman, thermogravimetric analysis, X-ray photoelectron spectroscopy, diffraction. Scanning electron microscopy, SDM, Brunauer–Emmett–Teller confirmed pores are mainly micro- mesopores less than 10 nm size, which results swift absorption oil HPGA2. SLS found have 90% particles below 35 μm, suitable for plugging microcracks formation. The impact on rheological characteristics assessed through performance test an emulsion breaking voltage test, respectively. evaluated via medium-pressure filtration high-temperature high-pressure simulated microfracture experiment. experimental show inclusion has minimal OBDFs; when added at level 2%, demonstrates outstanding compatibility OBDFs substantially cut down loss both standard high-temperature, environments; experiment microcrack plugging, pressure-bearing capacity fluid 2 wt % about times higher original fluid, while permeability decreased from 92 9%. This paper introduces technique fabricating composite exhibits superior sealing capabilities, providing way solve instability caused during drilling.
