Extraction of boron from soil by microwave heating for ICP‐AES determination

Abstract: Extraction with hot water is the most widely used procedure to determine boron (B) in soils for the diagnosis of the nutrient availability for plants. However, this procedure is tedious for routine conditions and requires some special precautions. An alternative extraction procedure was developed, consisting in the extraction of B with a 1.25 g/L solution of barium chloride (BaCl 2 ) or with water heated in a domestic microwave oven. Boron was determined either by inductively coupled argon plasma emission spec… Show more

“…The results of extractors and methods used to evaluate the micronutrient availability vary greatly. This was mainly due to the chemical composition of the extractors as well as soil characteristics, which influence nutrient dynamics and extraction efficiency directly (Abreu et al, 1994).…”

“…Para definir o teor de B no solo, utilizou-se o método proposto por Abreu et al (1994), o qual usou uma solução de cloreto de bário 1,25 g L -1 com aquecimento assistido em micro-ondas. Esse método ainda utiliza o reagente colorimétrico mais utilizado para a determinação de B em solo a Azometina-H. Para análise do teor de B no tecido foliar, foram coletadas as primeiras folhas maduras localizadas abaixo do ponto de crescimento da planta (Srivastava & Gupta, 1996).…”

“…The extractable soil Mn, Cu, Zn, and Fe content was determined by extraction with DTPA-TEA pH 7.3 (Lindsay & Norvell, 1978), and the extractable B content was determined by extraction with BaCl 2 .H 2 O 0.125% in a microwave oven (Abreu, Abreu, Raij, van, Bataglia, & Andrade, 1994).…”
