This study compared the performance of tannin (quebracho and spruce) iron sulphate (FS) coagulants for removal vanadium from effluent derived an abandoned mine. The efficacy materials was studied at natural pH mine (7.4), adjusted levels 4 9. quebracho coagulant (QT) recorded impressive turbidity removals above 88% over a wide range. However, spruce (ST) not as effective 9 (39%) although it showed improved 46% 70% 7.4 4, respectively. attributed to lower charge density ST than that QT, loss...
This study investigated the effect of seasonal variation (i.e. winter and summer) on tannin extracts from spruce bark as biocoagulants for water treatment applications. Tannins were extracted through three different extraction procedures: cold-water (21 °C), plus hot-water (85 °C) direct °C). 1H nuclear magnetic resonance spectra showed that extractions possessed highest proportion phenols. Electrospray ionization-mass spectrometry indicated a preliminary sufficiently reduced non-phenolic...
This study explored the potential of melamine, as nitrogenating source for cationization pulverized quebracho and spruce tannins. The influence modification conditions on properties coagulants was studied by varying formaldehyde melamine ratios with different activation times temperatures. Based considerations charge density shelf life, most viable modifications were established synthesized a 1:0.52 to molar ratio at 70 °C. At optimal conditions, 2.22 meq/g 1.04 meq/g, respectively, residual...
This work investigates the proanthocyanidin profile of willow bark crude extracts and these materials were cationized preliminarily tested as biocoagulants for water treatment. The characteristics investigated using size exclusion chromatography (SEC), nuclear magnetic resonance (NMR) X-ray photoelectron spectroscopy (XPS). XPS analysis indicates that contain significant amounts sugars. Furthermore, SEC liquid-state NMR showed extract contains roughly 3–4 flavan-3-ol units with procyanidin...

This study was carried out to investigate the potential of oil-free-cake dry seed kernels desert date (Balanites aegyptiacus (L.) Delile) for simultaneous removal Pb (II), Cu (II) and Cd ions from Battery Industry Effluent using standard methods in a batch sorption process.. The battery effluent mimicked by dissolving known concentration metal distilled water. optimum conditions were: pH (6), contact time (105 min) adsorbent dosage (6.5 g). results obtained showed that biosorbent effective...
