The ability to prepare solid surfaces with well-controlled superhydrophobic and superoleophilic properties is of paramount importance water–oil separation technology. Herein, we successfully prepared superhydrophobic-superoleophilic membranes by single-step deposition polystyrene (PS) nanofibers onto a stainless steel mesh via electrospinning. contact angles diesel water on the PS nanofiber membrane were 0° 155° ± 3°, respectively. Applications toward separating liquids low surface tension,...
This study is the first to demonstrate capability of Cl- markedly accelerate organic oxidation using thermally activated peroxymonosulfate (PMS) under acidic conditions. The treatment efficiency gain allowed heat-activated PMS surpass peroxydisulfate (PDS). During thermal activation at excess Cl-, accelerated 4-chlorophenol (susceptible by hypochlorous acid (HOCl)) was observed along with significant degradation benzoic and ClO3- occurrence, which involved oxidants low substrate specificity....
In fertilizer-drawn forward osmosis (FDFO) desalination, the final nutrient concentration (nitrogen, phosphorus, potassium (NPK)) in product water is essential for direct fertigation and to avoid over fertilization. Our study with 11 selected fertilizers indicate that blending of two or more single as draw solution (DS) can achieve significantly lower FDFO rather than using fertilizer alone. For example, KCl NH4H2PO4 DS result 0.61/1.35/1.70 g/L N/P/K, which comparatively them individually...
