First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: exposing a fluid sample comprising a metal to a chalcogenide compound having the formula (A x B x ′)M y Q z , where A is an alkali cation or an alkylammonium cation; B is an alkaline earth cation; M is Sn, Zn, P, Cu or Sb; and Q is S or Se, wherein the values of x, y and z can be the same or different; x, x′ and y can range, independently, from 0 to 9, provided that if one of x and x′ is zero, the other is not; and z can range from 1 to…
