Adsorption, viscosity and thermal behaviour of nanosized proteins with different internal stability immobilised on the surface of mesoporous activated biocarbon obtained from the horsetail herb precursor

Abstract The thermal analysis methods were used for the description of adsorption behaviour selected proteins differing in internal stability (ovalbumin (OVA) and lysozyme (LSZ)). These immobilised on surface activated biocarbon obtained from horsetail herb precursor. values hydrodynamic radius both biopolymer macromolecules solution determined by use viscosimetry method. This parameter is important specification possibility nano-molecules to penetrate nano-pores adsorbent which leads increase biopolymers adsorption. Such observed at pH value very close pI specific (the greatest carbon occurs- 5 OVA being 323 mg/g, as well 11 LSZ 464 mg/g). Under such conditions, assume conformations characterized lowest radius, i.e. 2.76 nm 1.07 LSZ. data gaseous products decomposition samples indicated types groups enabled protein mechanism.
