The sorption removal of cesium and strontium ions from chemically synthesized fibrous mordenite (M) and zeolite type ‘A’ in the form of honeycomb in seawater consisting of competing cations Na⁺, Mg²⁺, Ca²⁺, and K⁺ have been investigated. The batch experiments were carried out for the effect of various parameters such as initial contact time, uptake with volume mass ratio, distribution coefficients (K_d) factor, and effect on temperature. The uptake (%) of Cs⁺ ions for mordenite honeycomb at V/m=100 cm³/g was measured to be 86.8% and 57.9% within 18 h in pure water and 15 h in seawater media, respectively. On the other hand, the uptake (%) of Sr²⁺ ions for type ‘A&rs... view more»
