This article describes the commonly used experimental methods for assessing the biodegradability of polyacrylic acid polymers. It is recommended to use the carbon dioxide (PCD), oxygen consumption (COD) and infrared spectroscopy images of biodegradation to comprehensively analyze the biodegradability of polyacrylic acid polymers. The volume of the bioreactor is 2L, the concentration of the tested […]

2-Hydroxyphosphonoacetic acid is a good scale inhibitor. Its appearance is a dark brown liquid with a molecular formula of C2H5O6P and a relative molecular mass of 156.03. The preparation method generally has the following three methods. Method One 16.3 parts (0.11 mol/L) 50% aqueous solution of dihydroxyacetic acid (hydrated glyoxylic acid) and 8.2 parts (0.1 […]

Through the static scale inhibition test, we studied the scale inhibition performance of PBTC and HEDP on calcium carbonate scale under low-temperature conditions (2°C-15°C). The results show that the scale inhibition performance of PBTC and HEDP on calcium carbonate scale is good at 2°C-15°C. The initial calcium ion + alkalinity has a great influence on […]

The full name of DBNPA is 2-2-dibromo-3-nitriloproion amide. It is a broad-spectrum and efficient industrial fungicide. DBNPA is used to prevent bacteria and algae from growing in papermaking, industrial circulating cooling water, mechanical lubricants, pulp, wood, paint, and plywood. 2-2-Dibromo-3-Nitrilopropionamide (DBNPA) is currently popular at home and abroad. Organic bromine fungicides. Sterilization mechanism of DBNPA […]

1. The Introduction of Reverse Osmosis Chemicals The reverse osmosis chemical, IRASD-200 is a highly effective scale inhibitor developed for reverse osmosis (RO) systems. During the water treatment, dirt and iron scale are formed on the reverse osmosis membrane. They can degrade the performance of the water treatment system. Contaminants and deposits that accumulate on […]

2-mercaptobenzothiazole (MBT) is an important variety of thiazole rubber vulcanization accelerators. At the same time, it is also an important auxiliary agent for oxidation and corrosion resistance. 2-MBT is a pale yellow powder or granule. It has an unpleasant smell. The melting point is above 173.0°C. The relative density is 1.41 to 1.48. 2-mercaptobenzothiazole is […]

1. Active component (1-hydroxyethylidene-1 1-diphosphonic acid) content. 1.1 Oxidative decomposition method The active component of the finished product, 1-hydroxyethylidene-1 1-diphosphonic acid, and impurity phosphorous acid. Under appropriate oxidative decomposition conditions, both are converted to n-phosphonic acid. Then measure the data in a corresponding method. The total amount of n-phosphonate represents the amount of phosphinate which […]

The principle of testing is to convert 1-hydroxyethylidene-1 1-diphosphonic acid (HEDP) to ortho phosphorus. And then to measure phosphorous. The aim of the test is to detect the content of phosphorus (total phosphorus) in water. This testing is divided into two parts. They are inorganic phosphorus and organic phosphorus. The inorganic phosphorus portion may be […]

1-2-3-benzotriazole (BTA) is an organic compound. It is white to light pink needle crystal. 1-2-3-benzotriazole is soluble in alcohol, benzene, toluene, chloroform, dimethylformamide, and most organic solvents. However, it is slightly soluble in water, soluble in hot water, and easily soluble in alkaline aqueous solutions. 1-2-3-benzotriazole is used for surface purification of silver, copper, and […]
