Abstract:When Kayso is mixed with acid lead arsenate in absence of both hydrated lime and sulfur, large quantities of soluble arsenic are formed. Sti11larger quantities of soluble arsenic are released when Kayso is replaced by calcium carbonate. When powdered skimmed milk was substituted for Kayso, a decided reduction in soluble arsenic was found, while no decrease in spreading was observed. The addition of an excess of hydrated lime to the arsenical mixture greatly decreased the amount of soluble arsenic formed but did not entirely eliminate it. Sulfur alone, in absence of Kayso and calcium hydroxide, did not materially influence the decomposition of acid lead arsenate.
