在這篇論文中,採用動電位掃描和交流阻抗法評價了鍋爐主體系統溶液中水溶性咪唑啉緩蝕劑的緩蝕性能,並解釋了緩蝕機理。實驗得出影響咪唑啉緩蝕劑緩蝕性能的因素主要有溫度,濃度,預膜時間,並針對這三個因素的不同影響設計了多組模擬體系,驗證出該緩蝕劑是一種陽極型的緩蝕劑,緩蝕性能主要來自於吸附成膜後形成空間位阻,從而隔離了碳鋼基體和腐蝕介質。依據實驗數據計算得到其吸附能,從吸附能的大小可以判斷出吸附過程包含物理吸附和化學吸附兩種。實驗還表明預膜可以很好地阻礙腐蝕的過程,預膜後的碳鋼在含有很少量緩蝕劑的體系中就能較好地防止腐蝕,這樣就減少了緩蝕劑的用量,節約了資源。雖然預膜時間對自腐蝕電位的影響不大,但通過降低腐蝕電流密度和增大極化電阻的方式也起到了防腐功效。
Among the thesis, is it work up electric potential scan and exchange impedance law not to think boiler subject systematic solution water soluble miaow thiazole quinoline lose to lose performance slowly pharmaceutical slowly to adopt, and has explained the mechanism of losing slowly. It influences the miaow thiazole quinoline to lose slowly that the experiment is drawn the pharmaceutical loses slowly the factor of performance has temperature mainly, density, the membrane time in advance, and design many group's simulation systems for different influence of these three factors, is it is it should lose pharmaceutical to lose pharmaceutical slowly one positive pole type , lose performance is it is it form space location hinder after the membrane to absorb to come from mainly slowly slowly to appear to prove, thus isolated the carbon steel base body and corrode the medium. Calculate according to the experimental data that can absorb by it, can judge the course of absorbing and include physical absorption and chemistry and absorb two kinds from the size that can absorb. Experiment indicate membrane can hinder course that corrode well in advance , carbon in contain steel few quantity lose behind the membrane in advance also, rece the consumption of the pharmaceutical of losing slowly like this, economize resources. Though membrane time arises to the antiseptic efficiency by way of recing and corroding the density of the electric current and increasing the resistance of polarising to corroding the influence of the electric potential by oneself not big in advance.
在葯物毒性的體外實驗中,需要檢測化學葯物對細胞的增殖及存活的影響,不同於動物實驗可以直接觀察動物的生理現象,體外實驗需要檢測細胞存活率,而利用細胞某生命活動過程中產生的物質來檢測細胞是否存活及存活量。本實驗利用MTA法比色測定,用於測定H2O2對Hela細胞的毒性。
Need to examine the chemistry influence of medicine propagate cell and survival in the experiment outside the body of the medicine toxicity, differing from the animal experiment can observe the physiology phenomenon of animal directly, the body tests to need to examine a cell livability outside, but makes use of the output material in the cell some life movable process to examine cell whether survive and survive quantity.This experiment makes use of a MTA method ratio color measurement, useding for measuresing H2 O2's toxicity to Hela cell.
F. 高中化學各個實驗的注意事項和裝置圖
高中化學實驗的方法有哪些?做實驗的注意事項
我們從到了七年級就開始學習化學,但是學過的孩子們應該都知道,在初中只是先接觸一下,到了高中化學才開始真正的學習,但是學習化學就會做實驗,做實驗的方式都有什麼?

化學實驗儀器
在上面的文章當中我給你們說了很多關於高中化學實驗有哪些方法的類別,我相信大家應該也都知道了,每個實驗都有它適合的方法,你們一定要擇選適宜他的方式,還要注意一些事項.
G. 碘化鉀和氯化鐵反應實驗現象
該反應現象並不明顯,因為氯化鐵溶液本來就呈黃色或者棕黃色,欲觀察到專明顯現象,最好在溶液中加幾滴屬澱粉,將會觀察到溶液顏色變藍。
碘化鉀常用作鋼鐵酸洗緩蝕劑或者其他緩蝕劑的增效劑。碘化鉀是制備碘化物和染料的原料。用作照相感光乳化劑、食品添加劑,在醫葯上用作祛痰劑、利尿劑,甲狀腺腫防治和甲狀腺機能亢進手術前用葯物,也用作分析試劑。用於照相業作感光乳化劑,也用作醫葯、食品添加劑。

氯化鐵化學性質
1.與鹼反應
Fe3+ +3OH-=Fe(OH)3
FeCl3+3NH3·H2O=Fe(OH)3↓+3NH4Cl[2]
2.與還原劑反應
2FeCl3+SO2+2H2O=2FeCl2+H2SO4+2HCl
2FeCl3+H2S=2FeCl2+S↓+2HCl[2]
3.氯化鐵與烯醇類發生顯色反應
具有羥基與sp2雜化碳原子相連的結構( —C=C—OH)結構的化合物能與FeCl3的水溶液顯示特殊的顏色:苯酚、均苯三酚顯紫色;鄰苯二酚、對苯二酚顯綠色;甲苯酚顯藍色。也有些酚不顯色。[2]
4.鐵離子的檢驗
FeCl3+3KSCN=Fe(SCN)3+3KCl
溶液由黃色(Fe3+)變為血紅色[Fe(SCN)3]。

I. 實驗緩蝕劑有沒有效果常用方法有什麼
lan826酸洗緩蝕劑是比較常見的酸洗緩蝕劑,其實設備化學清洗不可或缺的化學品,但對於其添加量,根據不同的酸洗方式,添加量差異較大,鹽酸,硫酸等強酸酸洗添加量比較多,但是檸檬酸等有機酸酸洗的添加量比較少一些,但是lan826不能用於EDTA酸洗,另外欣格瑞的多功能酸洗緩蝕劑(液體)SGR-0405其添加量為無機酸(鹽酸、硝酸、硫酸、磷酸、氫氟酸等)使用濃度一般在3%-10%,不能超過20%,並且盡可能常溫使用,溫度超過55℃,否緩蝕劑易於失效;有機酸(氨基磺酸、檸檬酸、草酸、醋酸、EDTA等)使用濃度一般在3%-20%,常溫或加熱到60℃ -90℃使用,溫度或濃度不要太高否則緩蝕劑可能失效;初次使用可以根據試驗確定最佳使用濃度與使用條件。其添加量應該差不多
