Heterostructure‐Engineered Conductive MOFs Coupled with MoSe2@MXene Framework for Efficient and Selective Lithium Extraction from Salt Lake Brine via Capacitive Deionization

Advanced Science, EarlyView.
This schematic illustrates a capacitive deionization (CDI) system for the selective extraction of lithium from salt‐lake brine. The system employs a cathode fabricated from the Fe‐THBQ@MoSe2@MXene composite alongside an activated carbon (AC) anode. Upon applied voltage, the cathode demonstrates high efficiency in capturing Li+ ions while effectively ...

CO2 Adsorption on Mesoporous Silica Using Response Surface Methodology (RSM)

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The aim of the current study is to investigate the CO2 adsorption on the mesoporous silica. The adsorbent was characterized by XRD, TEM, SEM, and N2 adsorption desorption. The adsorption isotherms of carbon dioxide (CO2) on the silica were investigated using a static volumetric method at various temperatures.

Bioremediation of Crystal Violet Dye Using Sapindus mukorossi Functionalized Iron‐Oxide Nanoparticles From Coprecipitation Method

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The textile industry is a water‐intensive industry that disrupts aquatic ecosystems by releasing recalcitrant chemicals like crystal violet (CV) dye characterized by its carcinogenic and mutagenic nature. Ethanolic extract of saponin‐rich Sapindus mukorossi was employed in the synthesis of biogenic iron oxide nanoparticles (IONP).
