Opis

Zastosowanie

• Highly Efficient Recovery of Au(I) from Gold Leaching Solution Using Sodium Dimethyldithiocarbamate.: This study explores the effective recovery of gold using sodium dimethyldithiocarbamate in an ammonia-rich environment, highlighting the interaction with ammonia solution and its impact on the leaching process (Yang et al., 2024).


• Oxidation mechanism of pyrite in a thiosulfate solution: electrochemical impedance (EIS) and in situ Raman spectroscopy.: Explores the oxidation processes of pyrite in thiosulfate solutions facilitated by ammonia, examining the electrochemical properties and kinetics involved in the oxidation mechanism (Tamayo et al., 2023).

Opakowanie

Due to quality and safety aspects Ammonia Solution will no longer be offered in glass bottles but solely in HDPE bottles.

Please note the following replacements:
1054261000 (1 L glass bottle) replaced by 1054261011 (1 L HDPE bottle)
1054262500 (2.5 L glass bottle) replaced by 1054262511 (2.5 L HDPE bottle)
