This review reassesses groundwater's hydrochemical evolution in the Kaduna Basin using geochemical modelling (GM) and multiple regression analysis (MRA). Hydrochemical data were obtained from the literature using a systematic approach and were subjected to GM and MRA. The geochemical modelling results showed that aquifers are saturated with Anhydrite, Chlorite, Chrysotile, Dolomite, Gypsum, Halite, K-Mica, Pyrite, Quartz, Dolomite, and Goethite. The Na2O-Al2O3-SiO2-H2O system indicated that the studied locations fell in Na-montmorillonite and Kalinite fields. However, the K2OAl2O3-SiO2-H2O system showed that groundwater is stable with Montmorillonite, Kaolinite, and K-Feldspar. MRA and Na+/Cl- molar ratio revealed that rock weathering significantly controls groundwater. The Na+/Cl- values are above 1 in 83.33%, 54.84%, and 26.27% sampling locations in the Kudenda-Nassarawa area, Kaduna South, and Kakuri and its Environs, respectively. The overall p-value was less than 0.01 and R-Sq = 63%, suggesting that all elements significantly influence aquifers' hydrochemistry. Results of geochemical modelling, Na+/Cl- molar ratio, and MRA are concurrent as they both show silicate weathering as the factor controlling groundwater hydrochemistry. Thus, geochemical and multiple regression analysis offers a reliable and user-friendly tool for assessing aquifers' hydrochemistry. We hope this review's findings will stimulate other researchers to an analogous procedure in a forthcoming study on hydrochemical analysis, especially those from semi-arid environments.

CO2 capture and conversion technology are highly promising technologies that definitely play a part in the journey towards carbon neutrality. Releasing CO2 by mild stimulation and the development of high efficiency catalytic processes are urgently needed. The magnetic field, as a thermodynamic parameter independent of temperature and pressure, is vital in the enhancement of CO2 capture and conversion process. In this review, the recent progress of magnetic field‐enhanced CO2 capture and conversion is comprehensively summarized. The theoretical fundamentals of magnetic field on CO2 adsorption, release and catalytic reduction process are discussed, including the magnetothermal, magnetohydrodynamic, spin selection, Lorentz forces, magnetoresistance and spin relaxation effects. Additionally, a thorough review of the current progress of the enhancement strategies of magnetic field coupled with a variety of fields (including thermal, electricity, and light) is summarized in the aspect of CO2 related process. Finally, the challenges and prospects associated with the utilization of magnetic field‐assisted techniques in the construction of CO2 capture and conversion systems are proposed. This review offers a reference value for the future design of catalysts, mechanistic investigations, and practical implementation for magnetic field enhanced CO2 capture and conversion.

The prevalence of indoor air pollution, primarily stemming from human activities, has led to increasing concerns regarding elevated CO2 concentrations in indoor environments. Prolonged exposure to such environments has been linked to reduced productivity, headaches, nausea, and more severe health risks, such as Sick Building Syndrome. Consequently, the development of efficient methods to reduce CO2 concentrations in indoor air is of utmost importance. This review offers a comprehensive analysis of cutting-edge indoor CO2 capture technologies, delving into the adsorption performance of solvents produced via various techniques. Our findings highlight the emergence of innovative materials that significantly enhance the indoor adsorption process; nevertheless, further investigation into reaction kinetics and stability remains imperative for continued progress. Among the methods assessed, Thermal Swing Adsorption and Wet Impregnation demonstrate superior suitability for indoor CO2 capture applications. Importantly, this review also emphasizes the potential of novel ventilation strategies, incorporating both internal ventilation and CO2 capture devices, to not only reduce indoor CO2 concentrations but also promote energy efficiency in buildings.
