Kumar et al, “Lithium Recovery from Oil and Gas Produced Water: a Need for Growing Energy Industry”, ACS Energy Lett. 4 (2019). Extraction of Lithium from shale gas produced water is a relatively new and very interesting topic. Lithium is a very important element for battery technology.(11)D. L. Russell and J. J. Tiede, “Measurement Uncertainties in the Pollutant-Discharge Permit System”, Chemical Engineering, October 1978. This is an old paper, but useful. The uncertainty reported for Iron discharge in relation to compliance was found to be very significant. (12)T.
