The authors prepared basic yttrium carbonate, titanium-loaded yttrium carbonate and yttrium hydroxide and tested how well they remove arsenate from water. The titanium-loaded material had the highest capacity. Yttrium is the adsorbent, not a measured contaminant.
Key numbers
This paper reports no numerical findings relevant to yttrium exposure.
Methods (brief)
Co-precipitation synthesis, surface characterization and isotherm, kinetic, pH and competing-anion tests.
Evidence fitness
Off-topic for dietary exposure: an arsenic treatment materials paper that does not support dietary exposure or toxicity claims for yttrium.
Limitations
Yttrium release from the adsorbents into treated water was not reported. The work was funded by, and includes authors from, an electronics company research institute.
