“…The bands at 1629 and 1525 cm –1 may be assigned to C=O stretching and O–H bending vibrations, respectively. 24 , 25 Weak absorption peaks from 1150 to 1450 cm –1 were assigned to C–O bending vibrations. After adsorption, the peaks corresponding to 3280, 2915, 2848, 1379, and 1028 cm –1 were found to shift to 3224, 2910, 2778, 1370, and 1032 cm –1 , respectively.…”

Dewaxed Honeycomb as an Economic and Sustainable Scavenger for Malachite Green from Water

Dewaxed honeycomb powder (HCP) was used as a promising adsorbent for removal of malachite green (MG) from aqueous solution. Raw honeycomb was strategically dewaxed by petroleum ether, and the purified product was characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), pH zpc , and proximate analysis. A high uptake capacity (123 mg/g) was found at neutral pH. Experimental data follow pseudo-second-order kinetics ( k 2 as 0.45 × 10 –2 g/min/mg, R 2 = 0.986) and Langmuir isotherm with R 2 0.999. Thermodynamic parameters suggested a spontaneous (Δ G = −26.28 kJ/mol) and exothermic (Δ H = −11.61 kJ/mol) process, which suggests increased randomness (Δ S = 0.0486 kJ/mol) at the solid–liquid interface during the adsorption process. The material can be regenerated by ordinary salt solution (1 M NaCl) and efficiently reused for three cycles with a minimal loss in efficiency. Adsorption mechanism is proposed to be a combination of electrostatic interaction and π–π stacking between aromatic units of HCP and MG. Abundant availability, possibility of wax commercialization, economic sustainability, and comprehensive waste management make HCP an ideal choice for dye decolorization.

“…Then, the polarization data that was in the Tafel plot was extrapolated and analyzed using software nova 1.11 to get some corrosion parameters of ASTM A36 iron. The effectiveness values of the synthetic (fish-scale) inhibitor and food-grade inhibitor were calculated using Formula 1, as follows [14], [15], [16], [17], [18].…”

“…One such way is through the adsorption process on a metal surface. This process can reduce the corrosion rate by increasing or decreasing the anodic or cathodic reaction and decreasing the reactant diffusion rate, as well as the electric resistance of the metal surface [15]. The adsorption type of synthetic chitosan of fish scale and the adsorption type of food-grade inhibitors are examples of chemisorption, given the charge transfer that occurs between the inhibitor molecules in a 3.5% NaCl solution and on the surface of ASTM A36 iron to form a coordination bond.…”

Organic chitosan synthesized from fish scales and food-grade chitosan were investigated, via the potentiodynamic polarization method, as potential corrosion inhibitors on ASTM A36 iron in 3.5% NaCl solution. The results of the study revealed that chitosan, both food-grade and that synthesized from fish scales, inhibited the corrosion of ASTM A36 iron in 3.5% NaCl solution. The source of the chitosan did not have any effects on the chitosan’s behavior or potential. The inhibitor efficiency value increased as the chitosan concentration increased. The optimum concentration of the two types of chitosan was 3000 ppm; the inhibitor efficiency value decreased when the inhibitor concentration was increased to4000 ppm. This inhibitor efficiency value change occurred because at 4000 ppm, the inhibitor concentration exceeded the best conditions to form a protective layer on the surface of ASTM A36 iron. Chitosan is cathodic, regardless of the source, and both types of chitosan were similar in terms of polarization type, adsorption, and isothermal adsorption. The isothermal adsorption interaction of chitosan (from either source) followed Temkin-type kinetics with the ASTM A36 iron and had chemisorption characteristics.

“…Besides application of plant extracts as corrosion inhibitors, the employment of valueadded compounds originated from un-utilized biomasses [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] as anticorrosion substances extended the investigations to another promising and superior candidates. Their chemical structures, similar to those of traditional inhibitors, and the fact that they are generated from low-cost and abundant waste biomasses opened new strategies towards to circular economy happen.…”

Considering the fact that corrosion of metals and alloys presents a significant problem all over the world, the one of most recently utilized approaches to combat this problem necessitates the researches for employment of new materials, which satisfied the green chemistry idea. In this connection, the development of sustainable corrosion inhibitors is highly demanded due to the increasing of awareness of green chemistry principles not only in corrosion discipline, but also in all branches of science and technology. Due to natural and biological origin as well as their eco-friendly extraction, the plant materials and biomass derived from various waste sources could be applied as beneficial substances for metals and alloys protection in different corrosion environment. Therefore, this work reports the main findings regarding their employments as green anticorrosion substances.
