Ka hoʻohana ʻana o ka ʻōnaehana hoʻomaʻemaʻe kānana molekala i loko o ka ʻāpana hoʻokaʻawale ea
Hoʻohana ka ea i hoʻopaʻa ʻia e ka mea hoʻopili ea i ka alumina i hoʻāla ʻia e ka adsorbent a me ka sieve molekala e wehe i ka wai, carbon dioxide, acetylene, a me nā mea ʻē aʻe. Ma ke ʻano he adsorbent, hiki i ka sieve molekala ke adsorb i nā kinoea ʻē aʻe he nui, a he ʻano maopopo ia i ke kaʻina hana adsorption. ʻO ka nui o ka polarity o m...E heluhelu hou aku -
He mea ʻawahia anei ka zeolite maoli? Hiki ke ʻai ʻia?
He ʻawahia anei ka zeolite maoli? He mea ʻai anei? I ka makahiki 1986, ua luku ʻia ke kūlanakauhale nani holoʻokoʻa i ka pō hoʻokahi e ka hanana Chernobyl, akā naʻe, ua pakele nā limahana, a he mau kānaka wale nō i ʻeha a kīnā ʻia ma muli o ka ulia.
