The influence of seasonal changes on the formation of colloids and thin films of iron(III) hydroxide in Ob floodplain lakes

The research was conducted in the middle Ob floodplain. Several parameters (dissolved CO2, pH, conductivity, temperature, humin substances, Fe) were measured in six floodplain lakes in summer and autumn periods 2018. Temperature, conductivity and dissolved CO2 demonstrated the significant difference between these two samples.
