The binary libraries CQLJ.SolidsLib and CQLJ.RegularLib are stored in application specific folders. The program ChemEQL V3.2 is downloaded, installed on your computer and started by clicking into the respective ChemEQL icons on the right. Download the manual and a folder with example files.
Many representative examples are included demonstrating typical chemical problems. The program is currently in use in both teaching and research.Ī manual guides through the application in a practical way. xls or for import in a graphic program.ĬhemEQL is an extended and user-friendly version of the original program MICROQL by John Westall. Both libraries can be altered and extended with new reactions and stability constants. A second library contains more than 300 solubility products that can be introduced if solid phases are modeled. A library with over 1700 thermodynamic stability constants allows quick access, comfortable creation of input matrices and hence easy use of the program. Two-dimensional logarithmic diagrams, such as pe-pH (Pourbaix), or generally pX vs. Kinetic reactions can be simulated with one rate determining process in a system of otherwise fast thermodynamic chemical equilibrium. Corrections for ionic strength can be made and activities calculated. Adsorption on up to five different particulate surfaces can be modeled with the choice of the Constant Capacitance, Diffuse Layer (Generalized Two Layer), Basic Stern Layer, or Triple Layer model to consider surface charges. It handles homogeneous solutions, dissolution, precipitation, titrations with acids, bases, or other components. It calculates and draws thermodynamic equilibrium concentrations of species in complex chemical systems.
A Linux version can be provided on request.
The program is a stand-alone version of ChemEQL, and different versions for Mac (.dmg) and Windows (.exe) are available.
