Title: TURBIDIMETRIC DETERMINATION OF POTASSIUM IN LEAF TISSUES WITH SODIUM TETRAPHENYLBORON
Author: TUBINO, M
TORRES, JRD
Abstract: A turbidimetric method using sodium tetraphenylboron for the determination of potassium (K) in leaf tissues was investigated. Analysis of K was performed on soybean and coffee leaves. Results were compared with those obtained with flame photometry and a very good correlation was found. Using a spectrophotometer set at 420 nm and a 1.0-cm optical path cuvette, 1.0-mu-g/mL of K can be quantified. The method is recommended as an alternative to flame spectrophotometry.
