- Foliar Spray: Rapid nutrient absorption with 2–5% concentration solutions.
Water Treatment
- Heavy Metal Precipitation: Removes Pb²⁺, Cd²⁺, and Hg²⁺ with >95% efficiency at pH 8–9.
- Dechlorination Agent: Neutralizes residual chlorine in wastewater systems.
Pharmaceuticals
- Intermediate in magnesium-based antacids and electrolyte formulations.
3. Industry Case Studies
Case Study 1: Agricultural Boost in India (2024)
- Client: GreenFields Agro Ltd.
- Challenge: Low tomato yields (8 tons/ha) due to Mg/S deficiency.
- Solution: Applied 20 kg/ha magnesium thiosulfate during flowering stage.
- Result: Yield increased to 12.3 tons/ha (+54%), ROI 3.8:1.
Case Study 2: Wastewater Treatment in China
- Client: Shanghai WaterTech Co.
- Challenge: Pb²⁺ levels at 2.5 ppm (exceeding 0.1 ppm limit).
- Solution: 0.5 g/L magnesium thiosulfate dosage at pH 8.5.
- Result: Pb²⁺ reduced to 0.08 ppm, compliance achieved.
