ICP_OES 분석결과 _ atomic %로 환산

1. 데이터 (분석결과, mg/kg)

• Indium (In) = 674,816.9 mg/kg
• Gallium (Ga) = 181,915.3 mg/kg

---

2. 단위 변환 (mg/kg → g/kg)

1 g = 1000 mg 이므로,

• In = 674,816.9 ÷ 1000 = 674.8169 g/kg
• Ga = 181,915.3 ÷ 1000 = 181.9153 g/kg

---

3. 원자량 (Atomic weight, g/mol)

• In = 114.818 g/mol
• Ga = 69.723 g/mol

---

4. 몰수 (mol/kg) 계산

mol=질량(g/kg)원자량(g/mol)\text{mol} = \frac{\text{질량(g/kg)}}{\text{원자량(g/mol)}}mol=원자량(g/mol)질량(g/kg)​

• In 몰수 = 674.8169 ÷ 114.818 ≈ 5.878 mol/kg
• Ga 몰수 = 181.9153 ÷ 69.723 ≈ 2.609 mol/kg

---

5. 전체 몰수

총 몰수=5.878+2.609=8.487 mol/kg\text{총 몰수} = 5.878 + 2.609 = 8.487 \, mol/kg총 몰수=5.878+2.609=8.487mol/kg

---

6. Atomic % 계산

\text{at%} = \frac{\text{해당 원소 몰수}}{\text{총 몰수}} \times 100

• In at% = (5.878 ÷ 8.487) × 100 ≈ 69.3 %
• Ga at% = (2.609 ÷ 8.487) × 100 ≈ 30.7 %

---

✅ 최종 결과:

• Indium (In) ≈ 69.3 at%
• Gallium (Ga) ≈ 30.7 at%
