TD is performed at temperatures of 150–300 °C and, in contrast with SPME, the desorption can take a long time, up to 15 min. However, the high sensitivity of TD requires the use of an expensive unit in the GC setup, the thermal desorption system (TDS), or the thermal desorption unit (TDU).
Desorption does not require sodium cyanide, which reduces cost and averts pollution. Work Principle In gold electrowinning process,when the electrolysis equipment is added with anions which are more easily absorbed by activated carbons, Au（CN）2ˉ is replaced by anion and the gold desorption is achieved.

By coupling a square-wave PSWE with HER system in H-cell, we succeeded in achieving 10 mA cm −2 at a lower voltage of 1.15 V than conventional water electrolysis (1.85 V). It is noteworthy that this performance metric was achieved under conditions of a relatively considerable electrode distance and significant voltage drop.
