500g/L莠去津懸浮劑測定玻璃柱
500g/L莠去津懸浮劑測定玻璃柱 詳細(xì)信息：

名稱：不銹鋼柱或玻璃柱
固定液：3%聚乙二醇-20M
載體：Gas Chrom Q
粒度：80-100目
應(yīng)用：GB/T 22608-2008 莠去津懸浮劑


為了解決高含量莠去津懸浮劑容易析水的問題,利用流點(diǎn)法對莠去津懸浮劑的分散劑進(jìn)行初步篩選,根據(jù)Zeta電勢和粒徑大小,進(jìn)行優(yōu)化組合確定了分散劑的種類和用量;在此基礎(chǔ)上,結(jié)合莠去津懸浮劑熱貯后的物化性能,確定了500g/L莠去津懸浮劑的配方為莠去津原藥46.5%、SD-208為4%、乙二醇4.0%、黃原膠0.15%、有機(jī)硅消泡劑0.1%、苯甲酸鈉0.1%、去離子水補(bǔ)足,結(jié)果表明,該產(chǎn)品熱貯14d后,懸浮率95%以上,分解率5%,其他各項(xiàng)指標(biāo)均符合懸浮劑的要求。

Glass column for the determination of 500g/L atrazine suspension
Glass column for determination of 500g/L atrazine suspending agent Details:

Name: stainless steel column or glass column
Fixative: 3% polyethylene glycol-20M
Carrier: Gas Chrom Q
Particle size: 80-100 mesh
Application: GB/T 22608-2008 atrazine suspension


In order to solve the problem that high-content atrazine suspension agent is easy to separate water, the flow point method is used to initially screen the dispersant of atrazine suspension agent. According to the Zeta potential and particle size, the optimal combination is determined to determine the best dispersant. Type and dosage; on this basis, combined with the physical and chemical properties of the atrazine suspending agent after heat storage, the best formula of 500g/L atrazine suspending agent is determined to be 46.5% of atrazine original drug and 4% of SD-208. , Ethylene glycol 4.0%, Xanthan gum 0.15%, Silicone defoamer 0.1%, Sodium benzoate 0.1%, and deionized water make up. The results show that the product has a suspension rate of more than 95% and a decomposition rate of 5 after being stored for 14 days. %, other indicators meet the requirements of suspending agent.


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used a glass column and internal standard method to determine 500g/L atrazine suspension, with satisfactory results.
