产品名称 : PST033 | 草酸标准溶液 二水合草酸 Oxalic acid standard solution 执行标准:GBT601
产品品牌 : 飞净 PHYGENE

 

草酸又名乙二酸,广泛存在于植物源食品中。草酸是无色的柱状晶体,易溶于水而不溶于乙mi等有机溶剂,草酸根有很强的配合作用,是植物源食品中另一类金属螯合剂。当草酸与一些碱土金属元素结合时,其溶解性大大降低,如草酸钙几乎不溶于水。因此草酸的存在对必须矿物质的生物有效性有很大影响;当草酸与一些过渡性金属元素结合时,由于草酸的配合作用,形成了可溶性的配合物,其溶解性大大增加。1~2%浓度常用于组织切片漂白实验!

按照GBT601标准配制的摩尔浓度标注为 c(1/2 H2C2O4),滴定溶液实验室分析使用!


常温运输与保存,有效期12个月


Oxalic acid, also known as oxalic acid, is widely found in plant-derived foods. Oxalic acid is a colorless columnar crystal, easily soluble in water and insoluble in organic solvents such as ether. Oxalate has a strong coordination effect and is another type of metal chelating agent in plant-derived foods. When oxalic acid is combined with some alkaline earth metal elements, its solubility is greatly reduced. For example, calcium oxalate is almost insoluble in water. Therefore, the presence of oxalic acid has a great influence on the bioavailability of essential minerals; when oxalic acid is combined with some transition metal elements, due to the coordination effect of oxalic acid, a soluble complex is formed, and its solubility is greatly increased.
