Dehydration Process - One Step Closer

Hello guys,

I hope everyone's week has been busy and great! I came back to most of the micro plastics I extracted from the DI water to being completely dried out. I weighed each cup and wrote down my data. Once I did that, I had already poured some DI from last week so that way I can continue to extract the micro plastics.  I redid the process again but this time adding less DI water to each cup so that way the dehydration process wouldn't take as long as it did the last time. I extracted most of the micro plastics as I possibly could but there still remained some micro plastics in the sediment. :( I created a new set of rows of weighed out sediment so I can start extracting a new set of micro plastics using a Sodium Chloride solvent.

From my observations, I feel like DI water did a solid job with seperating the micro plastics from the sediment. That could be because of the density of DI water.

Next week I will reweigh the micro plastics once it has finished dehydrating. I will continue with extracting micro plastics from sediment using Sodium Chloride.

Week 9: Getting Close to Finishing Up!

Hi guys!

I am getting close to wrapping up my project, i'm sure we all are! All these conferences coming up may have us on the edge of our seats, but we got this! So far I have already let the micro plastics sit out so they can dry and be weighed out. So far I have gotten half of the micro plastics from the sediment and have seen great results from using DI water! Next week I will be using Salt Water to extract most of the micro plastics from the sediment. We will see which solvent works best!
