thank you!

2) Agricultural waste can be useful as a sorbent for removing hazardous chemicals. Rice bran (waste from rice processing) is to be used as a sorbent for Cu2+ removal in a waste stream. An isotherm experiment was performed at 25C using and initial Cu?* concentration of 300 mg/L. The experiment is performed in five, 0.25 + L glass bottles, each with an increasing conc. of rice bran. Using the model and examples in your book, find the Freundlich isotherm parameters logK and 1. Mass of rice bran (g) Initial Cu? Concentration (Co in mg/L) Cu+ equilibrium liquid phase conc.
