Natural groundwater colloids are significantly important since they are closely related with toxic substances migration in subsurface systems. In this paper, a cross-flow ultrafiltration (CFUF) system equipped with 100kDa cartridges was developed to enrich groundwater colloids and multiple analytical techniques were used to characterize colloid properties. Analytical techniques included scanning electron...
To explore the sorption phenomenon and mechanism between humic acid (HA) and Beishan granite (BsG), the influence of factors such as pH, contact time, ionic strength, temperature, HA concentration and solid-to-liquid ratio were investigated using the batch technique. The sorption process was significantly affected by pH and ionic strength. The maximum adsorption capacity of HA on BsG was approximately...
To prepare metal nanoparticles in organic–inorganic hybrid thin film, we investigated the incorporation of metal nanoparticles into dioctadecylamine (DOA)/12-molybdophosphoric acid (PMo 12 ) hybrid Langmuir–Blodgett (LB) film through in-situ reduction of PMo 12 in two routes. The growth of metal nanoparticles was characterized by UV–vis spectroscopy and transmission electron microscopy...
