Abstract
A hybrid functionalized lamellar comprises a layered double hydroxide and [Sn2S6]4− anions intercalated with the gallery of the layered double hydroxide to form a [Sn2S6]4− intercalated layered double hydroxide.
Claims5
A method of producing a [Sn2S6]4− intercalated layered double hydroxide and removing heavy metal ions from a solution comprising:
- synthesizing MgAl-LDH-CO3;
- synthesizing MgAl-LDH-NO3 by the exchange of CO32− anions by NO3− anions;
- synthesizing MgAl-LDH-[Sn2S6] by the exchange of NO3− anions by [Sn2S6]4− anions,
- wherein the MgAl-LDH-[Sn2S6] comprises [Sn2S6]4− intercalated layered double hydroxide intercalated with a basal spacing of 1 nm±10% to about 1.10 nm±10%;
- and
- treating a solution comprising heavy metal ions at a pH of about 4 to 12 with MgAl-LDH-[Sn2S6].
