Hello
I am developing a soil column experiment to study pharmaceuticals transport and attenuation.I would like to know If is better to use a glass or a PVC column to perform this experiment and why
I would be very grateful for any help
I think I would choose PVC if I was you, because of the cost and the ease of handling. You just need to pay attention to the PVC porosity.
Having troubles with glass in the middle of the experiment could be a big problem if the column is the way I imagine it.
I am a healthcare professional designer and I am using Glass pipe following either the HTM Code and Standards or the Plumbing Codes requirement because the system discharge flow within the pipe system is brought by chemicals.
You will be facing a problem with PVC pipe as it is not appropriate to use in the healthcare public health design. PVC pipe is using for the normal system discharge flow or just waste water.
I hope that makes sense.
Thanks and kind regards.
PVC is much cheaper, more durable and easier to use. However, it may adsorb organics. I suggest to test the material with your compounds of interest by making a cylinder with a sealed end, filling with solution at the appropriate concentration and letting it sit for 24 or more hours. Take a sample of the solution when you put it in, and then compare that concentration with the solution in the cylinder.
Perhaps at better option is to use Teflon, PTFE. I have used it with good results on volatile organics.
