Effects of eco-friendly inorganic inhibitors (i.e., calcium nitrate, zinc sulfate, sodium hexametaphosphate and sodium tetra-borate or borax) for the mild steel corrosion control in 1 M HNO3 solution open to air at 28±1 °C were studied using corrosion, inhibition efficiency, and corrosion potential tests. The corrosion rate of the mild steel is increased with increasing the concentrations of HNO3 solution from 0.01 M to 1 M. The uses of 200-2400 ppm of these inhibitors enhanced the corrosion resistance properties of the mild steel in 1 M HNO3 solution. The corrosion resistance property of the mild steel is generally decreased with increasing the concentration of all corrosion inhibitors used here. The most efficient corrosion inhibitor is found to be calcium nitrate and it is followed by zinc sulfate, sodium hexametaphosphate, and borax subsequently. Adsorption of these inorganic salts inhibitors on the mild steel surface obeyed Langmuir adsorption isotherm. Consequently, the corrosion inhibition mechanism of the four inorganic salts for the mild steel corrosion control can be explained based on the formation of the passive film. It is found from the corrosion potential measurement that the cathodic type of corrosion inhibition action was by calcium nitrate, whereas zinc sulfate, sodium hexametaphosphate, and borax are acted as a mixed type of the inhibitors in 1 M HNO3 solution. In summary, all four inorganic inhibitors utilized in the present study can be applied as an environmentally friendly inhibitor to control the corrosion of the mild steel in aggressive HNO3 solutions.

“…11,14 Various kinds of materials such as polyphosphates, polyphosphonates, polycarboxylic acids, and metallic cations like Zn 2+ and Cu 2+ have been widely studied as threshold inhibitors in the antiscaling applications. 14,15 However, phosphorus inhibitors have some fatal detrimental effects, such as secondary pollution, which causes their limited use in industry. So researchers, with the advancement of green chemistry, are looking for environmentally friendly and efficient inhibitors.…”

The inhibition behavior of poly(acrylic acid:2-acrylamido-2-methylpropanesulfonic acid:tert-butyl acrylamide) (PAAT) as an environmentally friendly terpolymer on the calcium carbonate scaling in artificial seawater was investigated using electrochemical and chemical screening methods. Therefore, the inhibition mechanism of PAAT was attributed to both threshold and chelating effect. However, the threshold effect had a higher contribution to the inhibition of CaCO3 scaling rather than the chelating effect. The greatest inhibition efficiency of PAAT was achieved at 2 ppm concentration. These results were confirmed by surface analysis methods including scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). Moreover, the chronoamperometry test revealed that PAAT has a better inhibition performance than both homopolymer poly(acrylic acid) and copolymer poly(acrylic acid:2-acrylamido-2-methylpropanesulfonic acid).

Poly(maleic anhydride‐alt‐vinyl acetate) (PMV) is used as a fine chemical in the field of biomedical. However, the techniques of PMV preparation have shortcomings like limited yield (Yp), complex post‐treatment and toxic solvents. Herein self‐stabilized precipitation (2SP) technique which possessed advantages of simple operation and post‐processing, non‐toxic solvent, and surface‐cleaned product is adopted to synthesize low number‐average molecular weight (Mn) PMV by tune‐up of reaction parameters. PMV with Mn of 2800–39,200 g/mol are successfully achieved. Furthermore, acidolysis kinetics of PMV is investigated centering on effects of Mn, acidolysis temperature, and initial concentration. All samples can undergo completely ring‐opening and the equilibrium pH of acidolyzed PMV is related to initial concentration irrelevant to Mn and temperature. Carboxylic degree (CD) varying rate and time of reaching equilibrium pH and 100% CD are impacted by Mn and temperature irrelevant to initial concentration. Finally, scale inhibition effectiveness of PMV with 2800 g/mol can be up to 53.69%, larger than that of commercial citric acid by about three times. This contribution supplies an easily operational and eco‐friendly process to obtain low molecular weight PMV which can be the scale inhibitor for industry and daily life, providing the quantization basis for hydrophilic functionalization of PMV.
