Oxygen flask combustion of sulfur drugs - Potentiometric Titration
Load 5ml0.3H2O2. To be finished burning, shaking, and for 15 minutes to absorb completely the cork with a small amount of water washing and nickel-chromium wire,[link widoczny dla zalogowanych], Taiwan and spread to absorb the liquid detergent, and with the amount of water to the quantitative transfer to a 100ml beaker Mu. Heating,[link widoczny dla zalogowanych], evaporation of water until the volume is less than 5ml. Let cool, place the beaker on a magnetic stirrer, add vitamin C of about 0.05g, stirring allows the dissolved and continued for several minutes. Add 3Oml ethanol and 1ml1.4 a six-ring = O, stirring, and then insert the electrode potentiometric titration. Commercial use of micro-level calculation = When the point size, find the content of the drug tested. If the sample is water-soluble sulfate (eg, quinidine sulfate]), can be called directly after the water sample 5ml, stirring solution, combined with 30ml of anhydrous ethanol, dioxane home 1ml1.4 a direct titration. (The switch 34) · 4I · Z7 - Volume 11 No. 5 paste cream of Modern Applied Pharmacy mumps Preparation and efficacy of Wang (Shandong indigo, l 【Medical College Hospital, then the state 256603) Zhaoyun Mei (Shandong access , l 【Regional Health School, Bin 25o005) 1 pull Langen prescription 100g, Po Public pod 100g, silence 100g, rhubarb 50g, Angelica 50g, the ball slices 10g, ethanol 98mI, sodium carboxymethyl fiber cable 50g, glycerol 150g, ammonia ketone 20g, Nipagin 1g, distilled water added to the 1000g. 2 ① Preparation of the CMC research shops and glycerol absorbed, add appropriate amount of hot distilled water to slowly soak 4h, to make it fully flooded expansion, if necessary, to take water bath @ the amount of ethanol added borneol, Nepal barrier dissolved, then add N ketone mix well. @ Take Ban Langen, Po Public pod, silence water to cook the second, the first 2h, the second mention 1.5h, fried crossing combined filtrate evaporated into concentrates of 1:1. ④ the rhubarb, Angelica crushed, screened and sterilized over 120 days (to take thousands of hot air sterilization, in the 1 ~ 0. A heating 3It). 5 usage will soar cream applied to the plastic film,[link widoczny dla zalogowanych], the share of slightly more than cheek swollen parts of the scope of medicine, 3 to 4 King / d. 4 4.1 Clinical efficacy criteria of Xinjiang police. L markedly reduce local pain medication 30rain, 2d fever swelling, 3d base more, with no complications and effective medication 30rain t pain relief, 3d fever swelling, 4d base more. Invalid: drugs do not relieve pain, 8d no fever within the non-swelling. 4.2 Treatment of results. 80 down 8 ~ 10a of the children were randomly divided into two groups, treatment group, 50 down,[link widoczny dla zalogowanych], the control group of 80 down. The results raise the table below for a drug treatment methods were quiet a few to vote no to teach effective topical treatment group 璺 japonica hinder garlic paste 3 King / d5O3080330] 218 scorpionfish 1822% 5 to discuss the rate of paste paste Ban Langen, dandelion detoxification, swelling to rhubarb Xiehuo cooling cooling to Coptis anti-inflammatory swelling, swelling and pain to self-Chih borneol Tongqiao stasis,[link widoczny dla zalogowanych], cool pain. Six drugs outside the shake, you can avoid the pain medication, but also rapidly effective, but also consistent with the traditional Chinese medical theory of disease outside rule. Ketone increases the permeability of drugs, alcohol can increase the viscosity of indigo methyl cellulose, glycerol and the moisture Jing, increase the stability of cream paste. Therefore, the moderate kwu cream paste, easy to spine cloth to clean, bear fruit quickly, drugs for a long time. Received H on: 199zi · 03-23 (on the next page 42) rejection of sulfuric acid standard solution titrant (0.01moI / L) t precision press law lessons 5mI calibration standard solution placed 100mI beaker of sulfuric acid, and then J0ln ~ . 30ml of anhydrous alcohol and 1ml1.4 a = oxygen has six rings, the P power mixer, and with the 0.01mol/LPb (NOa) 2 solution for titration. According to the end of volume measured the concentration of lead nitrate solution correction factor. Discussed for the absorption of hydrogen peroxide solution, you can make Ai income sulfate sulfur to form. However, the remaining hydrogen peroxide on the electrode film has a strong lead oxidation. Adding a certain amount of vitamin C powder for 34 weeks * body easily and effectively eliminate excess hydrogen peroxide. It was found that too much vitamin C do not interfere with the titration, and the protection of lead electrode film useful. By 0.01mol / L sulfuric acid titration, we compared the methanol, ethanol, a 1.4-dioxane Lan different kinds of organic solvents and water poured over the situation when the potential jump, draw a water ethanol (5: 30) can reach a larger jump. Analgin and atropine sulfate by 18 kinds of raw materials such as drugs and measurement system of Jing, the results show that the method to obtain instructions from Pharmacopeia method with consistent results, without sulfur content of sulfur drugs do not interfere with the determination.
