Abstract:
A simple algebraic technique is presented for computing the adjusted sodium adsorption ratio (SAR) index. The statistical formula presented in this note facilitates the computation of the adjusted SAR without the use of a look-up table, custom computer software, or the need to compute exact individual ion activity coefficients and complexes. A short data analysis example is also presented that demonstrates the application of this technique.
