新材料を小袋に詰め、汚染水に入れてかき混ぜるといった簡単な処理でヒ素を吸着する。例えばヒ素濃度が２PPMと高い汚染水から数時間で約90％を除去できる。これを繰り返すことでヒ素を大幅に減らせる。
一般的な吸着材のゼオライトはヒ素以外の様々な物質も取り込んでしまうため、処理後の廃棄物が膨大になる難点があった。開発した新材料は特
にヒ素を選んで吸着するため少量で済むという。化学処理でヒ素を取り出し、材料を再利用することも可能。ヒ素を吸着すると白色から青色に変化するため、汚
染を調べるセンサーとしても利用できる。
水処理プラントだけでなく個人レベルでも使えるため、途上国などで普及に取り組んでいく計画だ。
多くの方々のためにも安価で提供でき、かつリサイクル可能な形で実用化して欲しいですね。
NIMS is 06, announced that it has developed new materials that can be easily removed toxic arsenic from water. The inner wall of the bore hole of a number of open alumina fine structure and closely laid in preference to capture the arsenic compound. In Asia and Africa because it is extensively contaminated with arsenic groundwater to ensure that safe water and new materials.
Packed in a small bag of new materials, the adsorption of arsenic in only a few contaminated water and stir into. 90% can be removed from polluted water within hours of high concentrations of arsenic, for example 2PPM. Significantly reduce arsenic in repeating this.
A typical zeolite adsorbents because incorporates a variety of substances other than arsenic, which had enormous difficulty of treated waste. Development of new materials is living in a small amount, especially for adsorbing arsenic choose. Remove the arsenic in chemical processing, materials can be reused. Changes from white to blue to adsorb arsenic, can be used as sensors determine the contamination.
For use at the individual level as well as water treatment plants, and plans to tackle the spread, such as developing countries.
Can offer less expensive for many people, I want to be recyclable and practical form.
