  α-Cyclodextrin functionalized silver nanoparticles as …

  2022125 · 2.3. Synthesis of colloidal α-CD functionalized AgNPs. α-CD functionalized AgNPs were synthesized by reduction of AgNO 3 in the presence of NaBH 4 as a reducing agent and α-cyclodextrin (α-CD) as a stabilizing agent [37.]. Briefly, 2.0 mL solution mixture of α-cyclodextrin (1%) and 20 mL of ice-chilled NaBH 4 (2.0 mM) were taken in 50 mL …

  Recovery of Gold from Shanono Gold Ore Deposit Using α-Cyclodextrin ...

  There are two major gold recovery methods: the hydrometallurgical technique, which employs cyanide solutions, and amalgamation method, which involves mercury (Hg). These methods present considerable health, safety, and environmental concerns. Past applications of alpha-cyclodextrin (α-CD) on gold scraps show that α-CD is not only inexpensive, but is …
