Pokročilé sorbenty pro separaci mikroplastů z vod.
[Advanced sorbents for the separation of microplastics from water.]
Internal code: separace mikroplastů ; 2020
Technical parameters: Funkční vzorek reprezentuje separátor pro záchyt mikroplastů a příp. mikropolutantů z vod, který je tvořen na bázi modifikovaných bentonitů a zeolitů. Modifikace bentonitu byla založena na hydrodynamické separaci prachových částic udržujících se ve vznosu. Je prováděna opakovaným cyklem praní a dekantace bentonitu. Vlastnosti hydraulicky modifikovaného bentonitu a klinoptiolitu pro efektivní záchyt širokého spektra mikročástic různých druhů plastů o velikostním intervalu 30 – 500 μm jsou uvedeny v tabulce níže. Sorbent SBET (m2/g) Smeso (m2/g) Vtot (mm3liq/g) Vmicro (mm3liq/g) EXTRA 107 76 157 17 Klinoptilolit 33 21 114 6
Economic parameters: Přínosem funkčního vzorku vyvinutého sorbentu je efektivní záchyt mikroplastů z vod. Přímé ekonomické parametry nelze vyjádřit vzhledem k absenci konkurenčních komerčních zařízení pro odstraňování mikroplastů z vod.
