A python interface for water chemistry
Description
The goal of pyEQL is to provide a stable, intuitive, easy to learn python interface
for water chemistry that can be connected to a variety of different modeling engines
Specifically, pyEQL defines a Solution class to represent an aqueous
electrolyte solution. The Solution class allows the user to manipulate solutions as
Python objects, providing methods to populate them with solutes, calculate
species-specific properties (such as activity and diffusion coefficients),
and retrieve bulk properties (such as density, conductivity, or volume).
>>> from pyEQL import Solution
>>> s1=Solution({"Na+":"1 mol/L", "Cl-": "1 mol/L"})
>>> s1.density
<Quantity(1.03710384, 'kilogram / liter')>
>>> s1.conductivity
<Quantity(8.09523295, 'siemens / meter')>
>>> s1.osmotic_pressure.to('atm')
<Quantity(46.7798197, 'standard_atmosphere')>
>>> s1.get_amount('Na+', 'ug/L')
<Quantity(22989769.3, 'microgram / liter')>
pyEQL also includes a number of other utilities to support water chemistry analysis,
including a built-in property database of diffusion coefficients, activity correction
parameters, and other data on a variety of common electrolytes.
It is designed to be customizable and easy to integrate into projects that require modeling of chemical thermodyanmics of aqueous solutions. It aspires to provide a flexible, extensible framework for the user, with a high level of transparency about data sources and calculation methods.
Key Features
-
Build accurate solution properties using a minimum of inputs. Just specify the identity and quantity of a solute and pyEQL will do the rest.
-
"Graceful Decay" from more sophisticated, data-intensive modeling approaches to simpler, less accurate ones depending on the amount of data supplied.
-
Not limited to dilute solutions. pyEQL contains out of the box support for the Pitzer Model and other methods for modeling concentrated solutions.
-
Built in database containing hundreds of model parameters and physicochemical properties for different ions.
-
Units-aware calculations (by means of the pint library)
Documentation
Detailed documentation is available at https://pyeql.readthedocs.io/
