Porous boron nitride is, due to Porous boron nitride is, due to its unique physical and chemical properties, a very promising­ adsorbent. Moreover, by using a sustainable and economically attractive synthesis, it can become a­ competitor for the widely used activated carbon. This synthesis will be systematically optimized with­ respect to its material characteristics, such as specific surface area, pore volume and diameter, and­ functional groups on the surface. Moreover, insight in the effect of synthesis parameters on the­ material characteristics will be gained.­ The boron nitride will be subsequently used as adsorbent for the removal of emerging­ micropollutants from water, which is a rapidly emerging global problem. Because it would be a timeconsuming­ and expensive process to experimentally determine the adsorption removal for every­ individual micropollutant, a representative set of micropollutants will be selected to assess their­ adsorption removal. The effect of material characteristics and micropollutant properties on the­ adsorption performance will be investigated systematically to find the optimal material­ characteristics for efficient adsorption of the selected variety of micropollutants.its unique physical and chemical properties, a very promising­ adsorbent.
