Inorganic flocculants have been used in water treatment for many years and are typically composed of metal salts. The most commonly used inorganic flocculant is aluminum sulfate, known as alum.


H3NSO4 is a sulfur-containing acid, distinguishable by its unique composition of nitrogen, sulfur, and oxygen. It can be represented in its molecular structure as H3N-SO4, indicating the presence of the thiol group. The acid is known for its relatively high acidity, which allows it to donate protons readily in aqueous solutions. It presents as a colorless or pale yellow liquid with a pungent odor, characteristic of sulfur compounds.

The compound exhibits several advantageous physical and chemical properties. It has a melting point of approximately 205 °C and is highly soluble in water. This solubility enhances its usability in various aqueous applications, including cleaning and descaling solutions. In its pure form, sulfamic acid is a solid, but it can easily dissociate in solution to release hydrogen ions (H⁺), thus exhibiting acidic characteristics. Its pKa value is around 1.0, indicating it is a strong acid in terms of proton donation.


While active ingredients are vital, excipients also play a crucial role in pharmaceutical formulations. Excipients are inactive substances that serve various purposes, including aiding in the manufacturing process, enhancing stability, and improving bioavailability. They can include fillers, binders, preservatives, emulsifiers, and flavoring agents, among others. For instance, lactose and starch may be used as fillers in tablet formulations to achieve the desired bulk and shape.


The Role of PQQ in the Body


In the pharmaceutical industry, α-ketophenylalanine calcium is being explored for its potential in drug development.
