The chemistry of the Hispanic-American amalgamation process

Journal of the Chemical Society, Dalton Transactions, 1999
The chemistry of the Hispanic-American amalgamation or patio process for the extraction of silver has been studied through a laboratory model in which a suspension of silver sulfide in concentrated sodium chloride solution reacts with copper(II) chloride before being treated with mercury. Approximately 90% of the silver was extracted and separated as a

Amalgamation of Synthetic Biology and Chemistry for High-Throughput Nonconventional Synthesis of the Antimalarial Drug Artemisinin

Organic Process Research & Development, 2017
The development of a cost-effective process for the production of artemisinin, the precursor of all artemisinin-derived drugs, the first-line treatment for malaria, has been a long-pursued endeavor. The breakthrough achievement of coaxing genetically engineered yeast to express Artemisia annua genes for the commercial production of artemisinic acid, an

Exploiting the higher specificity of silver amalgamation: selective detection of mercury(II) by forming Ag/Hg amalgam.

Analytical Chemistry, 2013
Heavy metal ion pollution poses severe risks in human health and the environment. Driven by the need to detect trace amounts of mercury, this article demonstrates, for the first time, that silver/mercury amalgamation, combining with DNA-protected silver ...
