Version 4.6 Now Released!


Full 32-bit Architecture.

Windows WIN7 Compatible.

MINEQL+ is now even better. With version 4.6 you have better control of your data with long file names. Better control of  output devices. Better control of your system with a more stable installation.

Fitting within the Microsoft standards means that MINEQL+ will be here, as a research and teaching tool, for a long, long time.

In addition to Windows 7, version 4.6 will still support XP and all previous versions of Windows from 98 on up.

If you currently are a registered user of MINEQL+, upgrade pricing is available.

For upgrade pricing, see here.

Published research using MINEQL




 
 
 
  Sept-2007 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.

Sept - 1998 Version 4.0: Windows, 16-bit version released.  Numerical stability locked 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 work:

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

Early 1980's The USGS develops a chemical equilibrium program called WATEQ. Their work continues throughout the decade to provide critical review of thermodynamic data.

1980 MINEQL "+Stanford" (because of the work at Stanford University) provides electrostatic surface complexation reactions within MINEQL.

1975 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.

1972 REDEQL is developed by James Morgan and Francois Morel.  First chemical equilibrium program with a vast scope of application. Becomes the prototype for MINEQL.
