He is known for his work on the structure and adsorptive properties of carbons. They occur in high frequency in the adsorptive zone of the root. Montmorillonite is effective as an adsorptive of heavy metals. Hydrogen spillover is the most common example of an adsorptive spillover. Such zeolites have ion-exchange, catalytic and adsorptive properties. Mutations in the "ADCY10" gene are associated with an increased risk of adsorptive hypercalciuria. Breakthrough curves are important for adsorptive separation technologies and for the characterization of porous materials. The course of the adsorptive concentrations at the outlet of the fixed bed are monitored.
