BTA detection of acid pickling corrosion inhibitor

Acid pickling corrosion inhibitor BTA (Benzotriazole) is a commonly used corrosion inhibitor for metal surface treatment, which can protect metal surfaces from corrosion and oxidation. For the detection of acid pickling corrosion inhibitor BTA, the following methods can be used:

Infrared spectroscopy: The sample is tested using an infrared spectrometer to confirm the presence of BTA using its absorption peak at a specific wave number. This method is accurate, simple, and suitable for detecting the presence or absence of BTA.

Colorimetric method: The sample to be tested is reacted with a specific reagent to generate a colored product, and its absorbance is measured by colorimetry or spectrophotometer. This method requires the preparation of reagents and the reaction operation between reagents and samples, which is suitable for quantitative determination of BTA content.

Chromatography: Use chromatography techniques such as high-performance liquid chromatography (HPLC) or gas chromatography (GC) to separate and detect BTA in the sample. This method usually requires sample pre-treatment, such as extraction, concentration, etc., followed by separation and qualitative/quantitative analysis on a chromatographic column.

It should be noted that the specific selection of testing method depends on factors such as actual needs, equipment conditions, and sample characteristics. To ensure accuracy and reliability, it is recommended to conduct testing in a laboratory or professional testing institution, following the corresponding experimental methods and operating procedures.
