Embodiment Construction

[0012] The research process of the inventive method is as follows: at first, in order to satisfy the total chlorine content measurement requirement in the balanced salt solution for perfusion, the measurement process is first determined to accurately measure this product (balanced salt solution for perfusion) 10ml, add dextrin Add 5ml of the solution and 8 drops of dichlorofluorescent yellow indicator solution, and titrate with 0.1mol / L silver nitrate titration solution. Every 1ml of 0.1mol / L silver nitrate titration solution is equivalent to 3.545mg of chlorine. Among them, the preparation process of the dichlorofluorescent yellow indicator solution is: weigh 0.1g of dichlorofluorescent yellow and dissolve it in 60ml of ethanol, add 2.5ml of 0.1mol / L sodium hydroxide solution, dilute with water to 100ml, shake well, Instantly. The preparation process of the dextrin solution is as follows: weigh 2 g of dextrin, add 100 ml of water, stir while heating until boiling, and let co...

Abstract

The invention belongs to the technical field of total chlorine content determination of eye wash products in the pharmaceutical industry, and particularly relates to a method for determining the total chlorine content in a balanced salt solution for perfusion, which specifically comprises the following steps: precisely measuring 10 ml of balanced salt solution for perfusion, adding 80 ml of water and 0.1 ml of dilute nitric acid, adding 5 ml of dextrin solution and 8 drops of dichlorofluorescein indicating solution, and titrating with 0.1 mol / L silver nitrate titrating solution, thus the color of the solution finally becomes light pink. The method disclosed by the invention can be successfully used for determining the total chlorine content of the balanced salt solution for perfusion, is good through methodology verification, meets the determination requirements of the total chlorine content of the balanced salt solution for perfusion, realizes accurate control of the quality of the balanced salt solution for perfusion, and provides a basis for product quality and safety.

Description

technical field [0001] The invention belongs to the technical field of measuring the total chlorine content of eyewash products in the pharmaceutical industry, and in particular relates to a method for measuring the total chlorine content in a balanced salt solution for perfusion. Background technique [0002] The balanced salt solution for perfusion is prepared by sodium chloride 0.64%, potassium chloride 0.075%, calcium chloride dihydrate 0.048%, magnesium chloride hexahydrate 0.03%, sodium acetate trihydrate 0.39%, sodium citrate dihydrate 0.17% From a colorless clear liquid. Clinically, it is mainly used for intraocular or extraocular perfusion fluid in ophthalmic surgery, irrigation fluid for endoscopic surgery, and irrigation fluid for various bone and joint cavities. It can also be used for various surgical irrigation and irrigation that allow the use of electrolyte solutions. Washing, cleaning, etc., such as washing, rinsing or soaking of various body cavities, tiss...
