  2. 제1항에서 있어서, 제거된 상기 금속이온인 Ag인것을 특징으로 하는 방법.
  3. 제1항에서 있어서, 제거된 상기 금속이온인 Pb인것을 특징으로 하는 방법.
  4. 제1항에서 있어서, 제거된 상기 금속이온인 Cr(III)인것을 특징으로 하는 방법.
  5. 제1항에서 있어서, 제거된 상기 금속이온인 Zn인것을 특징으로 하는 방법.
  6. 제1항에서 있어서, 제거된 상기 금속이온인 Ni인것을 특징으로 하는 방법.
  7. 제1항에 있어서, 상기 알칼리 토금속 규산염 고체가 규산칼슘인 것을 특징으로 하는 방법.
  8. 제1항에 있어서, 상기 알칼리 토금속 규산염 고체가 규산마그네슘인 것을 특징으로 하는 방법.
  9. 제1항에 있어서, 상기 알칼리 토금속 규산염 고체가 구형태인 것을 특징으로 하는 방법.
  10. 제1항에 있어서, 상기 알칼리 토금속 규산염 고체가 분말형태인 것을 특징으로 하는 방법.
