Bicarbonate ions also serve as an important base in living tissue.

碳酸根离子也是活组织中的一种重要的碱。

Two approaches are employed to prepare thiocyanuric acid derivatized gold nanoparticles, including the direct reduction of gold ions by potassium bitartrate and NaBH〓 and then through ligand exchange reaction.

用两种不同方法合成了三聚硫氰酸衍生的金纳米粒子，包括由酒石酸氢钾直接还原金离子及NaBH〓还原金离子后经配体交换反应。

TEM images show that the formation of shaped Au nanoparticles has been achieved by reducing Au ions in the presence of TCA using potassium bitartrate as the reductant.

TEM图像显示在TCA存在下，酒石酸氢钾直接还原金离子后形成各种形状金纳米粒子。

We present a simple approach to determine the content of casein in crosslinked polyacylamide, i. e., protein molecules are complexed with copper ions by biuret reaction. The polymer containing proteins is cinerated at high temperature and then the residue is dissolved into nitric acid. Protein content is measured by determining concentration of copper ion in nitric acid solution using atomic absorption spectrum.

本文提出了一种在交联聚丙烯酰胺中测定酪蛋白的简便方法，即：利用双缩脲反应使蛋白质与铜离子络合，含蛋白质的聚合物在高温下灰化，残留物溶于硝酸，通过用原子吸收光谱测定硝酸溶液中的铜离子浓度来测量蛋白质的含量。
