In each test, investigators dissolved 4 g of PVP K-30 in 8 mL of a solvent and heated the solution until it boiled. } Cheesecloth has a larger mesh and cannot be used for this extraction. Breakage affects the extraction performance and hence is an important parameter. An ideal temperature of just above freezing (~2C) is needed for the paracetamol extraction. Ibuprofen (Ibf) is a biologically active drug (BADs) and an emerging contaminant of concern (CECs) in aqueous streams. Considering the molecular structure, COSMO performs geometry optimization and calculates the polarization charged density [, Using these interaction parameters, the chemical potential is calculated, which is further used to estimate AC, The aqueous phase inherent affinity of Ibf can be found by the evaluation of solvation energies [, The Ibf removal efficiency was calculated using the formula. The phase solubility diagrams indicated the formation of soluble inclusion complexes between the drugs and HPCD and CDSB, which was of 1:1 stoichiometry. Increased porosity exposes a greater surface area of the product to the dissolution fluid and encourages penetration and circulation of dissolution fluid into the mass due to capillary action.
