ACTIVATOR OF CARBON DIOXIDE ABSORPTION BY CHLOROPHYLL- SYNTHESIZING MICROALGAE
Journal Title: Environmental Problems - Year 2019, Vol 4, Issue 2
Abstract
The influence of nitrogen oxides on the СО2 uptake rate by chlorophyll-producing microalgae of Chlorella type was investigated. Experimental dependences of microalgae concentration growth over time under certain values of nitrogen oxides concentration in the culture medium were obtained. The mathematical model of microalgae biomass growth depending on nitrogen oxides concentration was developed. Based on the solution of the mathematical model and the obtained experimental data, the concentration of nitrogen oxides for the maximal microalgae growth was determined.
