Development of Novel "Sponge-Type" Sorbent for Elimination of CS: Preparation of Ammonium Molybdophosphate - Polyurethane Foam (AMP-PUF) Composite and its Sorption Behavior

Abstract:

Aiming to develop sponge-type sorbent, composite involving ammonium molybdophosphate (AMP) and polyurethane foam (PUF) was prepared. A 33 - 60 % (w/w) of AMP granule was kneaded with base-liquids of two-component rigid type PUF. The composite was able to selectively and quantitatively adsorb 0.5-500 µL of Cs⁺ from 10 mL solution of 500 µL of Na⁺, K⁺, Mg²⁺ and Ca²⁺as matrices ions; distribution coefficient (k_d) was 4.2 × 10⁶ and 1.3 × 10⁵ mL/g for without and with matrices, respectively. Maximum sorption capacity was of 42.9 mg/g.
