Model jsm 6610lv

The test set and the experimental arrangement for the adsorption process were established using the following equipment, materials, and reagents: RoTap (WS Tyler RX-29 model, serial number 28390), pH meter (VWR, model B10P), pH meter (VWR, model BP30Cl), magnetic stirring grate and magnetic stirring bar (3 cm; Fisherbrand, Shanghai, China, model Isotemp), analytical balance (Ohaus, model Adventurer Pro AC64C, Pine Brook, NJ, USA), mercury thermometers scale of −10 °C–110 °C (Chemillé en Anjou, France), 1000 mL beakers (Pyrex), 10 cm diameter funnels of separation (Pyrex), and a 10 cm diameter Whatman No. 40 filter paper.
The characterization procedures involved the use of the following equipment: a Cress Melting Furnace (model C1632, serial number 910), an analytical microbalance (Mettler Toledo, model XP-6, serial number B518889533, Greifensee, Switzerland), a Becomar (Gas Extraction Hood, model CP-180, Toluca de Lerdo, Mexico), a heating plate (LabTech, model EG20B, serial number 211202G13746, Hopkinton, MA, USA), an atomic absorption spectrophotometer (Agilent Technologies, model 55AA, serial number MY21040001, Petaling Jaya, Malaysia), and scanning optical microscopes (model JSM-6610LV from JEOL, Akishima, Japan and model Pro X from Phenom, Eindhoven, The Netherlands).

H13 steel (50 mm × 50 mm × 15 mm) was taken as the workpiece in this work. The surface of the workpiece was initially finished on a disk polishing machine (Radical Instruments, Panchkula, India Model: RPM-33D) to obtain a uniform machining surface as shown in Figure 3. Then, energy dispersive X-ray spectroscopy (EDS) (JEOL, Peabody, MA, USA, Model-JSM 6610 LV) was performed on a non-machined workpiece to determine its composition. The percentage of composition is presented in Table 1.
