PURECERAM

Overview

PURECERAM is a silicotitanate adsorbent developed by our unique method of manufactureing.
There are demands for decontaminating adsorbents in response to the accidents that took place at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Co.
Previously available crystalline silicotitanate adsorbents have high adsorption capacity for cesium, while having inferior adsorption capacity for strontium. PURECERAM has high adsorption performance for both cesium and strontium and therefore is able to adsorb and remove cesium and strontium simultaneously.
In addition, because of the ability to adsorb cesium and strontium in presence of sodium, calcium, and magnesium, PURECERAM is expected to have an effect in adsorbing and removing these substances in seawater.

Able to adsorb Cs and Sr simultaneously
