Alums are the special type of double salts of certain compounds with the general formula M(2)SO(4)M(2)(SO(4))24H(2)O Here M: monovalent cation link Na^(+) ,K^(+),Rb^(+),NH(4)^(+) M: trivalent cation like Al^(3+),Fe^(3+) or Cr^(3+). Pota
suggesting tree DOM fluxes may be substantial given the hypermaritime climate of the region. Condensed aromatics contributed as much as 38% relative abundance of spruce and hemlock bark leachates suggesting coniferous trees are potential sources of condensed aromatics to surface waters. Soil leachates ...
