3 Δεκ 2019 · The mass spectrum of chlorine is good example of molecular element. Chlorine has two stable isotopes; chlorine-37 (25%) and chlorine -35 (75%).There are five main peaks of isotopes of chlorine of various isotopic monatomic ions. [37 Cl 2] + m\z = 74 ( molecular ion) [37 Cl 35 Cl] + m\z = 72.
Runoff of organic chlorine from the lower layers of soil is about 0.01 g/m2yr, much smaller than from the top layer (0.2 g/m2yr). In fact, the concentration of organic chlorine decreases with depth as shown in Figure 3 for Skullebo (south of Linköping, S) and Klosterhede (DK). Figure 3.
26 Ιουλ 2005 · The chlorine-cycle in soil is described from a budget-perspective focussing on the interaction between organic and inorganic chlorine. The concentration and storage of organically bound...
20 Ιουλ 2023 · Across all sites, specific chlorination rates were correlated with soil moisture and in combination with the patterns on org. matter types, the results suggest an extensive Cl cycling where humus types and soil moisture provided best conditions for microbial activity.
Under the selected test conditions, the mass concentrations of Cl − and SO 42− are in the range of 1–100 mg/L, and the correlation coefficient R (Cl −) = 0.9998, R (SO 42−) = 0.9997. The detection limits for chloride ions were 0.005 µg/ml and 0.016 µg/ml for sulfate.
1 Δεκ 2001 · Natural inputs of chlorine (Cl) to soils come mainly from rainwater, sea spray, dust and air pollution. In addition, human practices, such as irrigation and fertilization, contribute significantly to Cl deposition. In the soil solution, Cl occurs predominantly as the chloride anion (Cl −).
