MA-202U (Macroporous Strong-Base Anion Exchange Resin)
Uranium shine radionuclide, mafi kusantar faruwa a cikin ruwan ƙasa fiye da ruwan saman, kuma galibi
samu tare da radium. Rage matsalar ruwa na iya buƙatar magani don cire uranium da radium.
Uranium yawanci yana cikin ruwa kamar yadda uranyl ion, UO22+, wanda aka kafa a gaban iskar oxygen. A pH sama da shida, uranium ya wanzu a cikin ruwan sha mai mahimmanci azaman hadaddun uranyl carbonate. Wannan nau'in uranium yana da alaƙa mai girma ga resins mai ƙarfi.
