Abstract: Provided is a method of easily producing scorodite which is stable and has excellent filtering properties with excellent reproducibility and without using complex operations, when processing arsenic that is included in non-ferrous smelting intermediates, and particularly when processing copper arsenic compounds in the form of an intermetallic compound. Scorodite is produced by a leaching step of leaching arsenic from a non-ferrous melting intermediate containing a copper arsenic compound in the form of an intermetallic compound in the presence of a sulfidizing agent and an oxidizing agent, a solution adjusting step of oxidizing trivalent arsenic to pentavalent arsenic by adding the oxidizing agent to the leaching solution, and a crystallizing step of converting the arsenic in the adjusted solution to scorodite crystals.

Abstract: A method is provided for compensating for clock drift error and movement error of an access terminal. A forward link error is obtained that is attributable to at least a first error (e.g., clock drift error) component and a second error (e.g., movement error) component. The first error component and the second error component are estimated based on the obtained forward link error. A receive clock of the access terminal is compensated based on a combination of the first error component and the second error component. A transmit clock of the access terminal is compensated based on a difference between the first error component and the second error component. The forward link error may include a timing synchronization error between the access terminal and an access point as well as a frequency synchronization error between a forward link frequency and a baseband reference frequency.
