An Indirect Colorimetric Method for Potassium Determination in Soil Using a Paper Device and Smartphone
This study presents a simple method for determination of potassium in microliter scale using a paper device together with a smartphone. The method begins with the ion-pair extraction of dibenzo-18-crown-6-K+ complex into dichloromethane with an excess amount of calmagite. The aqueous phase containin...
