  5. 제 1 항 내지 제 4 항중 어느 한 항에 있어서, 반응시, 알카리수산화물을 첨가함으로 일정한 pH값을 유지하는 것을 특징으로 하는 방법.
  6. 제 1 항 내지 제 5 항중 어느 한 항에 있어서, 금속들의 전기화학 씨리즈에서 카드뮴(-0.40볼트)와 금(+1.5볼트)사이의 산화-환원전위를 갖는 비철금속의 산화물 또는 수산화물을 사용하는 것을 특징으로 하는 방법.
  7. 제 1 항 내지 제 6 항중 어느 한 항에 있어서, 금속 Cu, Ag, Ni, Co, Sn, Pb, Sb, As 또는 Bi의 산화물 또는 수산화물을 사용하는 것을 특징으로 하는 방법.
  8. 제 1 항 내지 제 7 항중 어느 한 항에 있어서, 산화제, 특히 과산화수소 또는 그 알카리염을 0.5-5%(당에 대해)양으로 당 용액에 첨가하는 것을 특징으로 하는 방법.
