Four types of steel slag with different compositions were employed, and the slag occurred from the steelmaking process in Korea. To confirm the ion composition in steel slag, inductively coupled plasma ICP (Waters 600E/431/125, Waters) analyses was used. The ions of metal elements such as Ca, Mg, Al, Si, and Fe were found from spectroscopy. The contents are shown in Table 2 . The efficiency of extraction was estimated by comparing the result of ICP.
Waters 600e 431 125
Manufactured by Waters Corporation
The Waters 600E/431/125 is a high-performance liquid chromatography (HPLC) system. It consists of three main components: the 600E pump, the 431 detector, and the 125 integrator. The 600E pump is responsible for delivering the mobile phase at a controlled flow rate, while the 431 detector measures the absorbance of the sample as it elutes from the chromatographic column. The 125 integrator processes the detector signal and provides data analysis capabilities.

The ionic composition of CKD was probed
by X-ray fluorescence (XRF;
ZSX Primus, Rigaku) and ICP (Waters 600E/431/125, Waters) analyses,
and phase composition was probed by X-ray diffraction (XRD; X’Pert
PRO MRD, PANalytical) analysis in the 2θ range of 20–80°
at a scan rate of 6°/min. In addition to the components listed
inTable 3 , XRF confirms
various cations such as K, Ca, Si, Fe, and Al from untreated CKD.
The ions with relatively high proportion (approximately over 1 wt
%) are summarized inTable 3 . ICP analysis (Table 4 ) identified the key components of CKD as K, Ca, Mg, Al, Fe,
and Si, and XRD analysis (Figure 7 ) identified the major phases as KCl and CaO. Surface
changes induced by pretreatment with H2O were probed by
SEM/EDX mapping (S-4800, Hitachi). The corresponding sample was prepared
by mixing CKD (10 g) and water (100 mL) for 10 min, filtering, and
24 h oven drying of the residue at 105 °C.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
