A Gas Sensor for the Selective Detection of Volatile Organic Compounds
… how temperature control of functionalised silica adsorbents can be used to produce discriminable signals of VOCs. In this context, the VOCs of interest were benzene, toluene, ethyl benzene, para-xylene (BTEX), due to their proven toxicity and prevalence in human environments. With the aim …

CO2 Adsorption on Polyethylenimine-Impregnated Lamellar Silica
… efficient, amine-containing, lamellar structured silica adsorbents for CO2 removal. Seven different materials were prepared by impregnation of various amounts of PEI, over as synthesized, or partially extracted or calcined lamellar silica. Materials were characterized by powder XRD and SEM. CO2 …

Towards decomposition of phosphonates in water using catalytic membranes: paraquat on silica as a proxy
… is to conduct a feasibility study of using silica supported catalysts as membrane materials to treat wastewater containing phosphonates. Because adsorption confounds the ability to study phosphonate decontamination chemistry, an equally important but easier to study compound, paraquat …

DEVELOPMENT OF NOVEL ADSORBENTS FOR THE REMOVAL OF EMERGING CONTAMINANTS FROM WATER AND WASTEWATER
… synthesize various beta-cyclodextrin (BCD) based adsorbents by coating BCD onto different supports such as silica, filter paper, iron oxide, and zeolite, b) to perform batch and column experiments using the developed adsorbents, c) to evaluate the performance of the adsorbents in different water …

Examination of Silica Removal with Solids Recycle for Reverse Osmosis Pretreatment
… can include size, charge, or solubility. Silica (SiO2) is difficult to remove during water treatment because it can exist in ground and surface waters as various dissolved and particulate species, all of which are defined by different properties. Silica speciation is dependent on variables …
