本発明は浄水剤に関し、より詳しくは、水道水中の異臭

浄水剤に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a water purifying agent, and more particularly to a safe water purifying agent that efficiently removes residual available chlorine that causes off-odor taste in tap water.
〔従来の技術及び発明が解決しようとする課題〕近年、
環境汚染に伴う水源の水質の悪化が進むにつれ、水道水
の異臭味が問題となってきている。[Problems to be solved by conventional techniques and inventions] In recent years,
As the quality of water sources continues to deteriorate due to environmental pollution, unusual odor and taste in tap water has become a problem.

及び配管の錆に由来する鉄分(金気臭)が挙げられる。Odors and tastes include residual available chlorine (calky odor/chlorine odor) derived from chlorine used for disinfection, 2-methylisoborneol, diosmin, etc. derived from metabolites of organisms such as blue-green algae that occur in water sources. Musty smell/fishy smell)
and iron (metallic odor) derived from rust in piping.

・塩素臭を除去するには吸着除去作用を有する活性炭が
優れている。また金気臭は、その原因物質となる酸化鉄
粒子が比較的大きな粒子径を有するため、フィルター類
の濾過作用により比較的容易に除去することができる。Water purifiers for tap water are rapidly becoming popular in order to remove these unpleasant odors and tastes. Activated carbon and ion exchange resins are used as filter media in such water purifiers, and activated carbon, which has an adsorption and removal effect, is particularly effective in removing chlorine and chlorine odors. Further, since the iron oxide particles that are the causative agent of metallic odor have a relatively large particle size, they can be relatively easily removed by the filtering action of filters.

合はカルキ臭・塩素臭を効果的に除去できるが、少量で
は除去速度が遅く使用に耐えられない。However, most of these water purifiers are attached to a faucet, and are not suitable for use on the spot when making tea or coffee. Water pressure of tap water is 1 to 3 kg/-
Although it is possible to obtain a sufficient amount of water by passing it through a filter to remove iron oxide particles (recently, hollow fiber membrane type filters are used), it is portable and can be used on the spot. Drip type, tea bag type, pot type water purifiers, etc., can only provide a static water pressure of about 0.01 kg/ctA, so if you use a filter, you will not be able to obtain a sufficient amount of water. In addition, without a filter, the activated carbon and ion exchange resin themselves that are the filter media will leak into the water, which is not desirable from a safety standpoint. In addition, in the case of such portable water purifiers that can be used on the spot, there is the problem that bacteria will develop if used for a long period of time, so it is preferable to use a disposable type as much as possible, but in this case it is costly. Due to this problem, it is desirable to remove off-flavor components using as little amount of agent as possible. However, when activated carbon is used in large amounts, it can effectively remove chlorine odor and chlorine odor, but when used in small amounts, the removal rate is too slow to withstand use.
水の異臭味であるカルキ臭・塩素臭・カビ臭・金気臭の
中で最も9遍的に発生しているカルキ臭・塩素臭を除去

No. 9, JP-A No. 62-95194 discloses a technique that utilizes the reducing power of L-ascorbic acid as a means to solve these problems. However, L-ascorbic acid is a very unstable substance, and must be provided to users in a state where it is isolated from air using a method such as aluminum laminated packaging, resulting in high costs.
