Governing equations

The exact equations the solver works for a lithium sorption (dle) — the same math shown in the app's "Theory" panel, not a black box.

q_i=\dfrac{q_{max,i}\,b_i\,c_i}{1+\sum_j b_j\,c_j}\;\;(\text{competitive Langmuir})

\dot n_{i,loaded}=\min(q_i\,m_{sorbent},\,\dot n_{i,feed}),\quad \dot n_{i,raffinate}=\dot n_{i,feed}-\dot n_{i,loaded}

Parameters

sorbent_mass [kg, required]; optional isotherms {component: {q_max [mol/kg], b [affinity, m^3/mol]}} — defaults to a cited Li-selective/Mg-rejecting Al-sorbent screening isotherm on components 'li'/'mg'. Liquid-phase competitive Langmuir; 1 brine feed -> loaded (Li-rich eluate) + raffinate.
