This package implements single adsorption and multicomponent adsorption through Ideal Absorbed Solution Theory (IAST). Some major features are:

- Explicit single component adsorption properties: loading, bulk phase properties
- Multicomponent adsorption

## Examples:

```julia
using Langmuir

#example from doi.org/10.1002/aic.14684

v = @MultiSite{LangmuirS1,LangmuirS1} #we create a multisite model, consisting

x1 = [1.468
        0.024
        0
        7.891
        0.001645
        0]

x2 = [2.847
        0.028
        0.
        2.223
        1.228
        0.]

x3 = [2.581
        0.84
        0.0
        2.901
        0.021
        0.0]

#creation of isotherms from vectors or other iterables.
    #you can also use Langmuir.from_vec! or Langmuir.from_vec
    #to create (or fill) vectors from isotherm models
    m1,m2,m3 = Langmuir.from_vec(v,x1),Langmuir.from_vec(v,x2),AST.from_vec(v,x3)
    models = (m1,m2,m3)

#calculate loading of a single isotherm
    #there are also functions to calculate the reduced spreading pressure, and inverse algorithms
    l1 = loading(m1,p,T)
    kh1 = henry_coefficient(m1,T)
    lmax = saturated_loading(m1,T)

y = [0.5,0.25,0.25]
    T = 300
    p = 1000

#total adsorbed amount, fractions of adsorbed components.
    q_tot,x,status = iast(models,p,T,y) 
```
