Abstract: In this study, the influence of solution pH and ionic strength on sorption of chromate by surfactant-modified zeolite was tested. The sorption of chromate followed a Langmuir isotherm under different pH and ionic strength ...

Abstract: A radial unbalanced magnetic pull (UMP) can be produced by an eccentric rotor and leads vibrations in large hydro-turbine generators. The influence of nonlinear UMP on the radial vibration of ...

Abstract: Landfill leachate, often having high concentrations of metal cations, anions, and organic compounds, presents a great threat to nearby groundwater. Due to negative charges on soil particles, regular clay liners cannot ...

Abstract: The use of permeable reactive barriers (PRBs) for groundwater remediation is based on two distinct mechanisms: sorption and transformation. With sorption as the main mechanism, contaminants sorb on the PRB materials and ...

Abstract: Given the rapid advancement in the natural gas market, the existing volume-based trading system falls short of accurately valuing this commodity. This study focuses on addressing the economic challenges in pipeline operations ...
