A study was conducted to introduce porous amorphous chalcogenides as selective adsorbents for heavy metals. The study described three chalcogenides with the nominal compositions of K2SnSb2S6, Cs2SnSb2S6, and K2SnSb2Se6, featuring amorphous structures. A general equation for this reaction in which alkali metal polysulfides were produced along with A2S2O3 and CO2 byproducts. The porous amorphous chalcogenides were synthesized by adding inert soluble inorganic salts into the presynthesized compounds, flame melting/water quenching of the mixture and finally liquid extraction of the salt.
