Theoretical and experimental studies of direct contact membrane distillation (DCMD) using commercially flat sheet hydrophobic polyvinylidene fluoride (PVDF) membrane were investigated to remove boron from simulated and natural seawater. Mass transfer mechanism and theoretical flux were determined using the dusty-gas model (DGM). Mass transfer analysis showed that the combined Knudsen-molecular model...
The present survey highlights for the first time that glucamine-modified ordered mesoporous silica (OMS) type SBA-15 can be used as adsorbents for the uptake of boron from water. By means of X-ray diffraction, N2 adsorption–desorption, thermogravimetry and Fourier transform infrared, the structure and physicochemical properties of the materials were characterized. The behavior of the calcined and...
