Hardness is caused by divalent metallic cations.
The dose of anti-acid-alkali divalent ions in any water does not precipitate.
The rate of the coordination reaction between divalent metal ions and murexide in a water-in-oil microemulsion was determined by spectrophotometric technique to study the transport of the metal ions entrapped in the organogel formed by cationic surfactant cetyltrimethylammonium bromide.
an inorganic compound containing the divalent ion -O-O-.
The systems include pectin beads crosslinked with zinc or any divalent cation of interest, which beads are then coated with Eudragit TM -type polymers.
any of a class of organic compounds that contain the divalent radical -CONHCO-.
A divalent atom or radical.
In addition, divalent metal adduction provided improved positive mode ionization efficiency for these peptides.
The divalent radical UO22+.
