General description

Kaolin is hydrated aluminum silicate. Its water sorption isotherms, desorption isotherms, desorption enthalpy and entropy have been determined. The impact of its addition to styrene-butadiene rubber composites has been investigated. The thermal degradation of kaolin has been analyzed.

Application

Kaolin has been used:
  • For preparing synthetic turbid water that is employed to evaluate the biosorption capacity of Moringa oleifera leaves.
  • In combination with carrageenan to induce arthritic inflammation in a rat model for evaluating the activity of JAK3 (janus kinase 3) inhibitors.
  • In a study to assess its utility for microparticle-enhanced cultivation (MPEC) of 2-phenylethanol and 6-pentyl-α-pyrone.
