A Dynamic Laboratory Manual (DLM) has been developed to allow undergraduate students to rehearse practicals using virtual experiments, video clips and a range of assessment support. The DLM has been shown to be highly successful in its goals. In this

Potentiometric titrations of quartz, kaolinite, feldspar, and partially hydrolysed polyacrylamide... more Potentiometric titrations of quartz, kaolinite, feldspar, and partially hydrolysed polyacrylamide (HPAM), and sorption measurements of HPAM on the minerals, allows identification of the general mechanisms of polyacrylamide adsorption to aluminosilicates and quartz. Adsorption was monitored at the mineral solution interface by way of X-ray photoelectron spectroscopy (XPS). XPS spectra of the unreacted minerals show bands in the Ols, Si2p, Al2p,
