Water Treatment Flocculation: As a coagulant, iron chloride dihydrate efficiently removes suspended solids and phosphates from water, widely used in drinking water purification and wastewater treatment.
Metal Surface Treatment: Used for etching and surface cleaning of metals such as copper and stainless steel, it is a key chemical material in the manufacturing industry.
Chemical Synthesis Raw Material: As a basic iron source and catalyst, it participates in the synthesis processes of various dyes, pigments, and inorganic compounds.
Laboratory Analysis: Used as a standard reagent or testing agent in scientific research and quality inspection, for water quality analysis, teaching experiments, and other scenarios.
Q1: What is the main difference between dihydrate and anhydrous ferric chloride?
A1: The core difference lies in the water of crystallization. Dihydrate contains a fixed proportion of water of crystallization, making it more stable, less hygroscopic, and generally easier to use and store.
Q2: Will the product clump during storage? How can this be avoided?
A2: Slight moisture absorption is possible in humid environments. The key is to store it sealed in a dry, cool place and use it as soon as possible after opening.
Q3: What is its iron content? How is the dosage calculated?
A3: The theoretical iron content (as Fe) of ferric chloride dihydrate is approximately 34%. The actual content is subject to the quality inspection report, and the dosage must be calculated accordingly.
Q4: Can it be used in the food or pharmaceutical fields?
A4: It is not suitable for conventional industrial-grade products. If it involves special fields such as food or pharmaceuticals, please specify this, and we can assess and provide a higher-specification product.
