As shown in Figure 7, both samples are sharply oxidized at about 460°C, at a temperature lower than that for the oxidation of CNM generated in CVD processes using iron-group metals or their alloys as catalysts [58, 59].
A heterogeneous electro-Fenton process using iron loaded polyacrylamide hydrogels enhance the efficiency of the process with respect to homogeneous electro-Fenton and anodic oxidation technologies.
In the present study, the response surface methodology (RSM) model was applied to study and perform the treatment of real indigo dyeing effluent by continuous electrocoagulation process using iron electrodes.
In the hot gas desulfurization process using iron oxide sorbent, the regeneration of the sulfided iron oxide sorbent consists of two reactions: the oxidation of iron sulfide with air, and its reaction with the sulfur dioxide formed during the air oxidation.
In the present study, arsenic removal from potable water by a batch EC process using iron plate electrodes was investigated with respect to charge loading and effects of operating parameters such as current density, operating time, initial arsenic concentration, ratio of electrode surface area over volume (S/V), and electrode connection mode on removal efficiency of arsenic were evaluated.
The Coal-Direct Chemical Looping (CDCL) process using iron-based oxygen carriers has been developed as a coal conversion process with in situ CO2 capture.
The many points in the manuscript where coloured pigments applied in the painting process are layered over elements of text in black ink make it likely that some of the text copying process, probably using iron gall ink, preceded stages of production using coloured pigments.
Therefore, the equilibrium of adsorption processes of deflouridation using iron ore can be determined by either of the models.
Hence, the process of defluoridation using iron ore follows the Freundlich isotherm.
In the first stage, single effect factors such as initial pH (pHi), current density (j), electrode distance (d), rotate speed (n), Na2SO3 dosage (CS), and initial Cd2+ concentration (C0) in RDEC process are evaluated using iron disc as sacrificial electrodes.
The present study was undertaken to investigate the degradation and removal of direct yellow 9 (DY9) by the electro-Fenton (EF) process in batch reactor using iron and stainless steel electrodes.
