Popis

General description

Citric acid is one of the fruits acids. It is present in various citrus fruits and vegetables.

Application

Citric acid monohydrate has been used:

• as carbon source of carbon nanodot synthesis
• in the preparation of citric acid monohydrate solution/buffer of pH-6.0 for tissue sample preparation
• to treat various samples in citric acid solubilisation technique

Biochem/physiol Actions

Citric acid plays a major role in textile, food, pharmaceutical, metal and chemical industries. Melting citric acid monohydrate can give rise to itaconic anhydride. The crystals of citric acid monohydrate has the ability to preserve water up to 56 degree celsius.
