Full size image Whereas only 67.7% DCF was degraded in the group with higher concentration (80 mg/L) with prolonged incubation (24 h), and the degadation rate was lower. But at similar time more DCF at concentration of 80 mg/L was degraded, compared with the sample containing 20 mg/L ...
Distribution in nature. Rubidium is a typical dispersed element. Despite its relatively high concentration in the earth’s crust (clarke)—1.5 × 10-2 percent by weight, greater than the concentration of such metals as Cu, Pb, and Zn—rubidium does not form minerals of its own but rather ...
