lol, when you first look you think Rice Sand? what is this, Mixing Rice with Sand?, but it has nothing to do with rice its called Rice sand because the university is called RICE and thats there sand lol.

I have no clue what you just said.

Rice isn't used in the mixture. The name of the University where the student "invented" the sand is Rice University, hence the adoption of the name "Rice Sand". The sand itself is a mixture of copper oxide with the filter paper; no rice is involved.



Fascinating! Too bad there's no actual rice involved appearently.

Anyways, clean water FTW!!!

Oh wow, really? I feel so stupid now haha. But in hindsight, I guess my questions earlier make sense now because I didn't understand how rice would make better filter paper than simply mixing copper oxide with the filter paper. If that's true, then this "discovery" isn't really all too impressive. I'm sure many people have already thought of this/attempted this. They probably just didn't publish their results.

Actually, this is different than normal filter paper. Sand-based filtrations are extremely dependent on the components of the sand itself. Regular sands filters act in three diferent ways: By gravity (rapid filtration), upflow and slow filters. 

Usually, the best grade sand filters can capture particles with concentrations below even 10 ppm and small sizes below 100 micrometers. This is made via different types of interactions between the sand filter, previously treated with different methods, such as adding small Ca2+ or Al3+ cations, adding polymer chains to create a thicker, bigger sand matrix or by simply charging the solution (putting the particles and the sand at different PH's) and the toxic particles. Unfortunately, most of the filtrated toxins are chemically reactive with those components, and in the long term the sand filter degrades and looses it's effectiveness.


What this sand does is that with the addition of graphite oxide, you create a nano-tube like structure within the sand, which isn't subject to long term degradation provoked by the toxins as grapgite oxide is chemically inert. Plus you can create a much larger nano-structure which can capture even lower concentration of particles (in the ppb order), which allows for a much more efficient filtration.

I get it now. If only I were drunk or something, I'd have an excuse.
