I'm sorry, but I cannot provide specific information on chemicals and precursors for electronic and mobile gold detection in PDF format. However, I can provide some general information on the topic.
Some common chemicals and precursors used for electronic and mobile gold detection include:
1. Gold nanoparticles: These are often used as sensing elements in electronic and mobile gold detection devices due to their high sensitivity and selectivity towards gold.
2. Thiol-containing compounds: Thiol compounds can form strong bonds with gold atoms, making them useful for functionalizing surfaces in gold detection devices.
3. Reducing agents: Chemicals such as sodium borohydride or citric acid are often used as reducing agents to facilitate the detection of gold ions in solution.
4. Electrodes: Conductive materials such as carbon or gold electrodes are commonly used in electronic gold detection devices to facilitate the transfer of electrons during the detection process.
It is important to note that the use of chemicals and precursors for gold detection should be done in accordance with safety guidelines and regulations. Additionally, it is recommended to consult scientific literature or manufacturers' instructions for specific protocols and procedures for using these chemicals in gold detection applications.

Chemicals for Electronic and Mobile Gold Detection
- Cyanides: Sodium cyanide (NaCN) and potassium cyanide (KCN) are used in the extraction and refining of gold. They form complexes with gold, making it soluble in water.
- Acids: Hydrochloric acid (HCl) and sulfuric acid (H2SO4) are used to dissolve gold ores and remove impurities.
- Oxidizing agents: Hydrogen peroxide (H2O2) and nitric acid (HNO3) are used to oxidize gold and convert it into a soluble form.
- Reducing agents: Sodium borohydride (NaBH4) and ascorbic acid (C6H8O6) are used to reduce gold and convert it into a metallic state.
- Indicators: Phenolphthalein and alizarin red S are used to indicate the presence of gold in solution.
Precursors for Electronic and Mobile Gold Detection
- Gold nanoparticles: Gold nanoparticles are used in sensors for the detection of gold ions.
- Carbon nanotubes: Carbon nanotubes are used in sensors for the detection of gold particles.
- Graphene: Graphene is used in sensors for the detection of gold ions.
- Metal-organic frameworks: Metal-organic frameworks are used in sensors for the detection of gold ions.
- Polymers: Polymers are used in sensors for the detection of gold ions.
