摘要

在过去,我们永远无法想象购买饮用水。谁会买水喝?但现在,瓶装水几乎在世界任何地方都有销售,但仍有许多国家存在供水短缺问题。当饮用水被微生物污染时,它可能会接触到各种疾病,如肝炎、霍乱、腹泻和伤寒。我们不仅对饮用水感兴趣,而且对每个家庭的浴室、花园和洗衣房所用的水也感兴趣。我们提到“水质”是因为所有这些类型的水都足以给我们直接的刺激,比如气味和绿色。当我们在每家每户使用自来水时,最直接的刺激是“气味”。在这种情况下,我们首先想到的是氯,氯在消毒中非常有用。那么,为什么我们对饮用水或游泳池中的有毒气味敏感呢?答案很简单。氯消毒的效果只在清水中发挥,我们需要专注于余氯的分析,这对仪器分析很重要。因此,本研究中引入的是一种新的恒压方法的“余氯传感器”,它可以更准确地测量水中的余氯量,这是有效消毒饮用水的最重要因素。

INTRODUCTION OF RESIDUAL CHLORINE SENSOR USING CONSTANT VOLTAGE METHOD AND ITS MEASUREMENT PRINCIPLES
In the past, we could never imagine buying drinkable water. Who would buy to drink water? But now, bottled water are sold just about anywhere in the world, but there are still many countries with water supply shortages. When drinking water is contaminated with microorganisms, it can be exposed to various diseases such as hepatitis, cholera, diarrhea, and typhoid fever. We are not only interested in drinking water, but also the water used in bathrooms, gardens, and laundry of each household. We mention “water quality” because all of these kinds of water are enough to give us a direct stimulus such as odors and greens. When we use tap water in each household, the most direct irritation is the “smell”. In this case, we know that chlorine comes to mind first, and that chlorine is very useful in disinfection. Then, why are we sensitive to toxic odors in drinking water or swimming pools? The answer is simple. The effect of disinfecting with chlorine is only exerted in clear water, and we need to focus on the analysis of residual chlorine that is important for instrumental analysis. Therefore, what is introduced in this study is a “residual chlorine sensor” of a new constant voltage method that can be more accurate in measuring the amount of residual chlorine in water which is the most important factor when it comes to effectively disinfecting our drinking water.
