Penentuan Kadar Kalium pada NPK dengan Metode Sperktrofotometri Serapan Atom (SSA)

Abstract

Determination of potassium (K) in NPK fertilizers using atomic absorption spectrophotometry (AAS) at a wavelength of 766,5 nm has been done. From the analysis it can be seen that the levels of potassium contained in fertilizers NPK is 0,0886 ppm and levels of K2O in the fertilizer NPK 5,33%.
