Acid-activated kaolinite (AAK), prepared by the calcination and acid activation of coal-bearing kaolinite, was modified with TiO2 to improve its ability to adsorb and hence remove azo dyes. X-ray diffraction analysis, N2 adsorption–desorption analysis, and high-resolution transmission electron microscopy were used to characterize the synthesized samples and confirm the formation of anatase TiO2 nanoparticles...
W pracy zbadano wpływ dodatku minerałów ilastych do cementu, a mianowicie kaolinitu i montmorillonitu na właściwości zaczynu z równoczesnym dodatkiem superplastyfikatora naftalenowego. Przeprowadzone doświadczenia wykazały, że adsorpcja plastyfikatora przez kaolinit i montmorillonit, badane za pomocą spektrometru promieniowania ultrafioletowego, była mniejsza niż cementu. Jednak szereg właściwości...
