Evaluation of spent diatomite incorporation in clay based …
Diatomite, fossilized of microscopic plants, was used up to 20% while fiber up to 1%. Samples with 120 × 120 × 20 mm and 40 × 40 × 160 mm size were produced to do tests. In addition to XRF, XRD, TGA and SEM investigations of diatomite, physical, mechanical and thermal test were done on produced samples.

Natural diatomite process for removal of radioactivity from liquid
The liquid waste contained three radionuclides (Cs-137, Cs-134 and Co-60). Following the treatment by diatomite, the radioactivity of liquid waste was reduced from the initial 2.60 Bq/ml to less than 0.40 Bq/ml. The results of this study show that most of the radioactivity was removed from the solution by processing with diatomite.
