In silico package models for deriving values of solute parameters in linear solvation energy relationships

, 2023
Environmental partitioning influences fate, exposure and ecological risks of chemicals. Linear solvation energy relationship (LSER) models may serve as efficient tools for estimating environmental partitioning parameter values that are commonly deficient

Characterization of surface properties of nitrogen-enriched activated lignites by spectroscopic and chromatographic coupled with LSER modelling measurements

Fuel Processing Technology, 2002
One investigated way to prepare selective adsorbents towards mixtures of volatile organic compounds (VOCs) is to modify lignite by nitrogen-enrichment. These chemically modified coals are prepared by condensation of urea with the lignite before the carbonization/activation steps. This study describes a set of analytical tools able to explain in term of
