The processes of exchange and sorption of orthophosphoric acid on Amberlite IRA-402 were studied. The concentrations of phosphate phosphorus and hydrogen ions were determined in initial and equilibrium solutions. It was found that there is a linear dependence between the amounts of phosphorus exchanged and/or sorbed in the model system tested (Amberlite) and the quantity and concentration of H3PO4...
It is well known that effective exchange of metabolites between mitochondria and the cytoplasm is essential for cell physiology. The key step of the exchange is transport across the mitochondrial outer membrane, which is supported by the voltage-dependent anion-selective channel (VDAC). Therefore, it is clear that the permeability of VDAC must be regulated to adjust its activity to the actual cell...
The influence of artificial aeration on chemical composition of bottom sediments and nutrient exchange was investigated in heavily polluted Lake Długie. Analyzed were variations in the content of nitrogen and phosphorus compounds in near-bottom water, interstitial water and bottom sediments. The obtained results have confirmed a positive role of many years’ artificial aeration in reducing the internal...
