Characteristics of dextrin adsorption by elemental sulfur were investigated by the means of diffuse reflectance infrared Fourier transform (DRIFT) spectroscopy, total organic carbon (TOC) measurements, BET measurements as well as molecular dynamics simulation (MDS). Adsorption isotherms for dextrin adsorption by sulfur were compared to isotherms for dextrin adsorption by other hydrophilic and hydrophobic surfaces taken from the literature. The three-dimensional structure of dextrin was studied in detail and possible mechanisms of adsorption are discussed. Additionally, molecular dynamics simulations provided further insight into the mechanism of dextrin adsorption by elemental sulfur.
