(OH) 2CO3, FeSO4/7H2O (light green), F2 (light yellow green), Cl2 (yellow green), chlorine water (pale yellow green) Red: CuO, Cu, Fe 2 + (SCN), methyl orange, purple litmus test solution in the acidic environment in the acidic environment, phenolphthalein, magenta in alkaline ...
The study was performed for searching optimum values of FeSO4 and H2O2 concentration, pH and temperature. The H2O2 requirement seems to be related to initial COD of the sample. FeSO4/ H2O2 ratios found were not changed for the temperature affected the COD removal significantl...
Zn + H2SO4 = ZnSO4 + H2 up with a large number of bubbles and zinc particles gradually dissolve the laboratory to prepare the hydrogen Fe + H2SO4 = FeSO4 + H2 up with lots of bubbles and metal particles dissolve Mg + H2SO4 = MgSO4 + H2 up with lots of bubbles and metal...
CuSO4+K3Fe(CN)6→FeSO4+K3Cu(CN)6 What is the color of : 1.K3Fe(CN)6?2.K3Cu(CN)6? Chemical reaction Chemical reactions are generally characterized by the occurrence of the physical as well as chemical changes. Inorganic chemical changes, organic...
1.The catalytic mechanism of Fe 2+ in the H 2O 2 bleaching ofcoloured wooland the influence of processing parameters on the Fe 2+ absorption of wool are investigated in the paper.本文探讨了Fe2+在有色羊毛双氧水脱色中的催化作用机理,并通过对处理液中Fe2+含量的定量分析,研究了FeSO4浓度、处理时间...
Whereas, in combination with FeSO4, it has shown the highest removal efficiency of 96.5%, 83% and 75% for respective parameters at the optimal dose of 40 mgL-1 + 3 ml FeSO4 (1 M) in comparison with other processes. A seed germination test using seeds of Spinach (Spinacia oleracea) ...
