Thiosulfates/Dithionites/Polythionites TRIZ Cases
- Sodium Dithionite Stabilization Using Carbonates and Complexing Agents
See how alkali metal carbonates and complexing agents reduce sodium dithionite decomposition, p
- Cobalt Sulphate-Dithionate Liquor Processing for Water and Salt Recycling
Precipitating cobalt, then crystallizing and heating sodium salts, enables water recycling and energy-efficient cobalt and lithium recovery.
- Two-Step Sulphide Leaching to Cut Cyanide Use
An acidic then alkaline oxidative leach converts elemental sulfur to thiosulphate, improving precious metal recovery while cutting cyanide use.
- Anhydrous Sodium Thiosulfate Formulation for Pediatric Ototoxicity
Anhydrous sodium thiosulfate formulations help protect pediatric hearing after platinum chemotherapy while preserving anticancer efficacy.
- Ammonium Salt Production via Sour Water Stripper Gas Pre-Treatment
Liquid-liquid coalescers remove organic compounds from sour water before steam stripping to enable efficient ammonium salt production.
- Ammonium Thiosulfate Tail Gas Treating for Sulfur Recovery
Ammonium thiosulfate solution absorbs sulfur dioxide from Claus SRU off gases, reducing energy consumption compared to thermal SCOT-TGTU processes.
- Continuous Calcium Thiosulfate Production via CSTR Oxidation
Continuous stirred tank reactors oxidize calcium polysulfide to high-purity calcium thiosulfate, destroying polythionates for metal leaching.
- Thiosulfate Polymer Gate Dielectric for Low-Voltage OFETs
Crosslinked thiosulfate polymer gate dielectrics enable low-voltage organic field effect transistors on flexible substrates without high temperature processing.
- Sodium Hydrosulphite Stabilization via Benzoic Acid Additives
Adding benzoic acid and oxalic salts to sodium hydrosulphite prevents spontaneous combustion during storage.
- Precipitated Alumina Neutral pH Seeding Process
Neutral pH seeding and precipitation phases yield high surface area alumina without acidic conditions.
- Calcium Thiosulfate Production via SO2 Absorption
A contactor reactor mixes sulfur dioxide with lime slurry to produce concentrated calcium thiosulfate while minimizing byproduct formation.
