How to identify the quality of polyaluminum chloride

Release time:2024-02-20 Number of visits:343

Polyaluminium chloride water treatment agent is a necessary chemical agent in the process of industrial water, domestic water and wastewater treatment. Through the use of these chemicals, the water can meet the inevitable quality requirements of water treatment agent. The identification of true and false can be intuitive from its appearance, color, smell, solubility, clarity and solid crystal form.


So what method can distinguish the authenticity of polyaluminium chloride water purifying agent? Generally, we start from the following four aspects:

1、 Determination of physical constants. Such as the density and viscosity of liquid reagent, the melting point of solid reagent, etc

2、 Acquisition of spectra or other spectral features.  For example, ultraviolet absorption spectrum, infrared spectrum and nuclear magnetic resonance spectrum. For some drugs, their chromatographic characteristic values (specific shift value, retention time, etc.) can also be determined

3、 PH value. Generally, it is based on the pH value of 1% aqueous solution

4、 Major chemical reactions. Such as functional group reaction, ion reaction, etc.
