Reliable supplies of metals have historically been the keys to industrial and technological development. But many metals are subject to the possible exhaustion of traditional kinds of deposits. A continued supply of such metals, which include tin, tungsten, silver, lead, zinc, and many others, will require their recovery from common rocks, in which...
Measurements of H2O2 in rainwater collected in Miami, Florida, and the Bahama Islands area indicate the presence of H2O2concentration levels ranging from (1–7)×10−5 M. No systematic trends in H2O2 concentration were observed during an individual storm, in marked contrast to the behavior of other anions (e.g., [NO3 −], [SO4 =], and [Cl−]). The data ...
