White arsenic Refined

The refined arsenic trioxide is analysed for purity and also tested for solubihty, a term referring to its rate of reactivity with nitric acid this test is important if the arsenic is used in the manufacture of insecticides and herbicides. The product is graded for marketing as white soluble having 99% min AS2O2, white insoluble, or cmde having 95% min AS2O2. [Pg.328]

Termites are a serious problem in several known limited areas and are on the increase. White refined arsenic has been used in Cuba with some success but has not resulted in control. Treatment of 13,000 infested acres required 1800 pounds of arsenic in 1953. Dieldrin and similar compounds appear more promising at present. Aldrin (hexachloro-diendomethano-hexahydronaphthalene) has been used at the rate of 2 pounds per acre on 750 acres in the Dominican Republic with good results. Termites do not seem to be a general hazard at this time. [Pg.17]
