Description Usage Arguments Details Value Author(s)
Permeability coefficients across a membrane as derived from integrated Fick's law can be obtained from transport data according to the equation
\ln{\Bigg(\frac{C}{C^0}\Bigg)}= \frac{P~a}{V}t
where P is the permeability coefficient, a is the membrane exposed area, C and C^0 are the species concentrations at any time and at initial time in the feed phase, respectively, and V is solution volume.

Units in which volume, area and time are provided. Volume
and area are function's parameters while the time is
extracted from the

Initial concentration of the species in the feed solution. The
value may be extracted from transport information if the data

Species concentration units may be arbitrary as long as the permeability coefficient is calculated using the change in concentration ratio which is, as most ratios, adimensional
A numeric vector with the permeability coefficient and it's standard uncertainty from the regression. Units are meters per second.
