An improved process for the removal of cyanide ion from aqueous dispersions (e.g., aqueous spent cadmium plating solutions or plating rinse water solutions) is provided wherein a source of Feion is reacted with a cyanide ion-containing a... GH Zaid,BA Wolf - US 被引量: 7发表: 2002年...
A number of marine water and fresh water samples were examined for the relative O 18 O 16 ratio, and the variation of this ratio was determined to a precision of ± 0.1%. In the case of surface marine waters, for a range of salinity of 29.40%., the O 16 content varies over a rang...
Atmospheric water vapor content, which reflects the total change of water vapor in the whole atmosphere, has an important effect on the atmospheric visibility (VIS). To investigate the variation of the VIS in Beijing during the past decades and to address the key factors affecting the VIS, the...

The test of Cd pollution black soil freezing/thawing at different frequency cycles and the different water content were carried out with 24h as one freeze/thaw period. The content of exchangeable form Cd and organic binding form Cd all presented marked relations (P0.01) with the freeze/thaw fre...
Abstract Environmental factors play an essential role in the etiology of diseases of the hematopoietic system. Such factors include soil and water pollution and the presence of metals and toxic compounds in the air. Measuring the content of metallic elements in rainwater has become an accepted proced...
