Abstract

Boron is an essential nutrient for plants and an essential element for many organisms, but can be toxic to aquatic and terrestrial organisms above certain concentrations. The aim of this research is determining the Boron content of four varieties of Hazelnut (Corylus avellana L.) from Sakarya. Inductively coupled plasma optical emission spectrometry (ICP-OES) with ultrasonic nebulization (USN) was used for the determination of Boron contents. This method is based on microwave digestion system and reduced memory effect of Boron by using sorbitol. Different conditions were optimized for this method. Four hazelnut varieties, eight soil samples and certificated reference material (NIM-GBW10012) were analyzed. The Boron contents were found as 18.27, 28.3, 38.6, 17.6 mg/kg in Kara, Sivri, Delisava and Tombul hazelnut varieties, respectively. And Boron contents of soil samples were between 30.44 to 196.79 mg/kg. The results revealed that the Turkish hazelnut is a good natural source of Boron.

微波消解-超声雾化-电感耦合等离子体发射光谱法测定榛子中硼
硼是植物的必需营养素,也是许多生物的必需元素,但在特定浓度以上,对水生和陆地生物可能有毒。本研究的目的是测定四个品种榛子(Corylus avellana L.)的硼含量。采用超声雾化电感耦合等离子体发射光谱法(ICP-OES)测定硼含量。该方法基于微波消解系统,利用山梨醇降低硼的记忆效应。对该方法的不同条件进行了优化。对4个榛子品种、8个土壤样品和NIM-GBW10012标准物质进行了分析。卡拉榛子、西夫里榛子、Delisava榛子和汤布尔榛子的硼含量分别为18.27、28.3、38.6和17.6mg/kg。土壤硼含量在30.44~196.79mg/kg之间。结果表明,土耳其榛子是硼的良好天然来源。
