よく知られている事実である。It is also a well-known fact that iron tannate powder or granules are packed inside cigarette filters and chemically adsorb harmful substances such as nicotine, phenolic substances, and aldehydes generated during smoking.
これらの事実は何れもタンニンキレート化合物単体の粉
体又ｔｌ顆粒として使用されている。All of these facts are that the tannin chelate compound is used as a single powder or TL granule.
タンニン酸と例えば塩化第二鉄とのキレート化合物（タ

の超微粒子の状態で集めて吸着剤として使用すること祉
極めて困難である。Chelate compounds of tannic acid and, for example, ferric chloride (iron tannate) are extremely fine particles suspended in a reaction bath, and it is extremely difficult to collect them in the form of ultrafine particles and use them as an adsorbent.
その為に反応浴中の条件を規制して微粒子同志を７０ツ
キングさせ粒子を生長させたあと、沈澱、濾過、乾燥し
そのま＼粉体として使用するか、要すれば粉砕して粒度
を揃え使用するのが通例である。For this purpose, the conditions in the reaction bath are regulated to allow the fine particles to stick together 70 times to grow the particles, and then the particles are precipitated, filtered, and dried, and then used as is as a powder, or if necessary, crushed to make the particle size uniform. It is customary to use
この為に使用するに際し、反応生成時の超微粒子よりは
るかに粒径が大きく比表面積が低下し、化学的吸着能が
極端に低減することになる。When used for this purpose, the particle size is much larger than the ultrafine particles produced by the reaction, and the specific surface area is reduced, resulting in an extremely reduced chemical adsorption capacity.

せたこと′ｔ−特徴とするものである。The present invention focuses on the binding of paper fibers and tannins,
Paper is immersed in an aqueous tannin solution to bind tannin to the fibers, and then immersed in an aqueous solution of a substance that chelates with the tannin to form a chelate compound on or between the fibers.'t-Characteristics That is.

たらすことができる。The chelate compound bound to the chemisorption paper of the present invention is formed on fibers or F
i Since the adsorbed substance is bound to fibers, when the adsorbed substance passes between or penetrates the paper waste, there is an extremely large chance that the adsorbed substance will come into contact with the chelate compound, and the amount of adsorption per unit weight of the chelate compound is It can bring about a huge improvement compared to conventional products.
キレート化合物を結着させている基体が紙であることか
ら紙の気孔度厚さなどを規制することによって粉体物質
も併せてキャッチすることができる。Since the substrate to which the chelate compound is bound is paper, powder substances can also be captured by controlling the porosity, thickness, etc. of the paper.
キレート化合物は紙の繊維上又は繊維間ｋかなり強固に
結着されているので過電の酸アルオリ液中ではキレート
化合物は脱落すみことは殆んどなく、液相においても高
効率の性能を発揮することが可能である。Since the chelate compound is quite firmly bound on the paper fibers or between the fibers, the chelate compound hardly falls off in the overcharged acid-aluminum solution, and exhibits high efficiency even in the liquid phase. It is possible to do so.
した、密度０４以下透気度ｌθ０秒以下の多孔質で湿潤
強度を持たせた紙が好ましい。It is preferable to use porous paper having a density of 04 or less and an air permeability lθ of 0 seconds or less and having wet strength.
使用するタンニンは加水分解型が好ましく、その精製度
は用途と経済性を勘案して選定するのが良い。The tannin used is preferably a hydrolyzed type, and its degree of purification is preferably selected in consideration of the intended use and economic efficiency.
