In the present work we investigate the influence of the degree of crystallinity of graphite on the production of graphite oxide (GO). Graphite precursors with varying degrees of crystallinity were produced by milling a high-purity synthetic graphite powder during different times and the milled materials were used for the synthesis of GO, using a modified Hummers method. The products were characterized...
The enthalpies of micellization for the anionic surfactant sodium dodecylsulphate (SDS) in water and in NaCl solution have been studied by calorimetry at 298 K. The calorimetric experiments were carried out by measuring the heat of solution of SDS in both monomeric and micellar phases. From these data the enthaply of micelle formation was derived. The enthalpy of solution of SDS below and above...
