滴定

Just prior to the analysis, prep a re the test solution by adding 0.5ml of the bromophenol blue indicator solution to each 100ml of the aqueous acetone solution and titrating with 0.01 N HCl or 0.01 N NaOH until the test solution is just yellow in color.

分析前准备好测试溶剂，100ml含2%水的丙酮加到锥形瓶中，加0.5ml 1%溴酚蓝水溶液指示剂，用0.01N NaOH溶液滴定至绿色或蓝色，然后用0.01N 盐酸标准溶液滴定至刚好呈黄色

In some range,the addition of chitosan and titriable acidity after deacidification appears linear correlation,1 g chitosan can absorb 0.41 g titriable acidity, but chitosan only can absorb citric acid and malic acid, and it has no effect on quinic acid.

在一定范围内，壳聚糖的加入量与降酸后酒液的滴定酸呈线性关系，1 g壳聚糖可以降低0.41 g／L的滴定酸，但壳聚糖只能吸附主要有机酸中的柠檬酸和苹果酸，对奎尼酸无作用。

Therefore can pass to use the cupric sulfate sulfuric acid potassium for the catalyst take sulfuric acid as to carry the body to digest it, make the amino acids chelate match the conversion for dissolve sex easily of ammonium sulfate and white vitriol, then absorb a fixed amount to try the kind to join 40% sodium hydroside combine under the steam heat function make ammonia the spirit swims to leave out, through cool off to respond the born boric acid with boric acid, be got the total nitrogen content by the standard aqua titration of hydrochloric acid immediately after;But the white vitriol can immediately join the hydrochloric acid hydroxylate , fluoride to turn the in order to cover up, carry on the titration but get the content of its zinc with the EDTA mark liquid..

因此可以通过用硫酸铜硫酸钾为催化剂以硫酸为载体将其消化，使氨基酸螯合锌转化为易溶性的硫酸铵和硫酸锌，然后吸取一定量的试样加入40 %的氢氧化钠并在水蒸气高温作用下使氨气游离出来，经冷却与硼酸反应生成硼酸铵，接着由盐酸标准溶液滴定得到总氮含量；而硫酸锌即可加入盐酸羟铵、氟化氢铵为掩蔽剂，用EDTA标液进行滴定而得到其锌的含量。

Methods: Glass electrode,iodometric method,disodium EDTA titration,silver nitrate titration,fluoride ion selective electrode.

There are three purity measuring methods of vulcanizing accelerator NOBS : potentiometric titration , indicator titration and liquid chromatography .

硫化促进剂 NOBS 纯度的测定方法有三种：电位滴定法，指示剂滴定法和液相色谱法。

Objective To establish a method for uncertainty evaluation in nonaqueous titration with perchloric acid.

摘 要 目的通过高氯酸液滴定药物含量不确定度的评价，建立普遍适用于滴定法测定药物含量的不确定度评定方法。

The paper studies the color range of papaver rhoeas red pigment under pH values, and compares it with the other indicators by the acid-base titration.

本文研究了虞美人色素在不同pH值溶液中的颜色变化，并通过虞美人色素和其它指示剂进行酸碱滴定的比较，结论为：虞美人色素能准确指示酸碱滴定的终点，其变色范围pH 6.33~8.25，颜色由紫红色变为棕色
