Analisis Unsur Hara Tembaga (Cu) yang terkandung dalam Daun Kelapa Sawit PT Riau Sakti United Plantation Perkebunan Secara Spektrofotometri Serapan Atom

Abstract

Having done analysis of cuprum element that was found in the leaf of oil palm in Pusat Penelitian Kelapa Sawit (PPKS) Medan. The treatment is done by drying the leaf samples and grinding. Then using micro digestion method with solvent HNO3(p) and HClO4(p). Analysis of Cu content was determined by measuring the concentration using Atomic Absorption Spectrophotometer instrument at a wavelength of 324,8 nm. From the results obtained by the analysis of Cu levels are 7-15 ppm. Content is in compliance with the standards of 4-15 ppm set by PPKS.
