摘要: Abstract Dry ashing and wet acid digestion of selected plant tissues were conducted evaluated for their effectiveness in the spectrophotometric determination boron (B) using Azomethine‐H method. In dry ashing, two parameters varied: aids length oxidation period. digestion, different mineral acids used period was varied between 12 24 h. Results showed that samples treated with sulfuric had lowest recoveries B. Boron concentrations oxidized h digestions at least 40% higher than results obtained any technique.
