Vista compatible, 32-bit, version 4.6 is released. |
May - 2002 Version 4.5: Thermodynamic
database is upgraded, documented and conforms to USEPA standards.
All reaction data is referenced.
- 1998 Version
4.0: Windows, 16-bit version released. Numerical stability
in for wide range of chemical conditions. New report writing
features. Titrations, sensitivity
analysis, processing of huge datasets now possible.
June - 1992
Version 3.0: DOS, 8-bit version is released. First spatial user
interface for MINEQL. Tableau view of input
data. Object oriented management of output data to fit any
application. MINTEQ data is included.
Prior to our
Late 1980's USEPA
combines MINEQL numerical code and the USGS's WATEQ thermodynamic
data to produce MINTEQ.
1987 At MIT, Dave
Dzombak collects Two Layer surface complexation data for a wide range
of aqueous ions on FeO
The USGS develops a chemical equilibrium program called WATEQ. Their
work continues throughout the decade to provide critical review of
MINEQL "+Stanford" (because of the work at Stanford University)
electrostatic surface complexation reactions within MINEQL.
MINEQL is developed at MIT, by John Westall and Francois Morel. The
FORTRAN program uses a generic tableau
approach to describe equilibria and mass balance in aqueoous systems.
REDEQL is developed by James Morgan and Francois Morel. First
chemical equilibrium program with a vast scope of application. Becomes
the prototype for MINEQL.
