“…This aligns with the presence of calcium carbonate as the primary compound in the study. It is important to note that at temperatures exceeding Additionally, peaks are evident in the curve between 2800 and 3000 cm −1 , at 1030 cm −1 , and between 850 to 700 cm −1 , which are consistent with H-O, P-O, C-H, and C-O related to hydroxyapatite, bearing similarity to the hard tissues of human bones and teeth as reported by Wang et al [51].

This study explored the potential of coral rock, specifically coquina derived from oyster shells, as a bioadsorbent for the removal of dyes from wastewater generated by the textile industry. The investigation included an examination of particle size fractions (300 µm and less than 300 µm) and thermal treatment; the investigation involved drying at 120 °C and calcination at temperatures ranging from 200 °C to 800 °C. The material was subjected to a comprehensive analysis through various characterization techniques. Laboratory-scale experiments were conducted to evaluate the removal capacity and adsorption kinetics of the bioadsorbent utilizing brilliant green dye. The experiments involved varying dye concentrations (25, 50, and 75 mg L−1), pH levels (2 to 12), and different doses of biosorbent material (0.2 to 0.6 g L−1), with constant agitation. Various kinetic models were applied to fit the experimental data, with the pseudo-second-order model demonstrating the best fit. The findings reveal that coquina rock, characterized by a temperature of 120 °C and a particle size of greater than 300 µm, exhibits remarkable effectiveness. It achieved a removal efficiency of 90% within 15 to 20 min at pH 7.8. This study concludes that coquina rock not only stands out as demonstrating remarkable efficacy in dye removal but also underscores a sustainable approach, leveraging readily available and environmentally friendly materials for wastewater treatment.

“…Biological calcium carbonate has already received a considerable amount of attention, striving, in particular, to improve the sustainability of the materials' production with inexpensive secondary raw materials, hence not affecting resource depletion [15]. Potential was also demonstrated in several applications, including, e.g., energy storage in batteries, considering its electrochemical stability [16]; water treatment and antibacterial action with silver nanoparticles [17]; the synthesis of hydroxyapatite for non-biomedical purposes, such as dye absorption [18]; and the production of bio-calcium oxide into industrial furnaces [19], or carbon-derived catalysts [20].…”

Natural and renewable sources of calcium carbonate (CaCO3), also referred to as “biogenic” sources, are being increasingly investigated, as they are generated from a number of waste sources, in particular those from the food industry. The first and obvious application of biogenic calcium carbonate is in the production of cement, where CaCO3 represents the raw material for clinker. Overtime, other more added-value applications have been developed in the filling and modification of the properties of polymer composites, or in the development of biomaterials, where it is possible to transform calcium carbonate into calcium phosphate for the substitution of natural hydroxyapatite. In the majority of cases, the biological structure that is used for obtaining calcium carbonate is reduced to a powder, in which instance the granulometry distribution and the shape of the fragments represent a factor capable of influencing the effect of addition. As a result of this consideration, a number of studies also reflect on the specific characteristics of the different sources of the calcium carbonate obtained, while also referring to the species-dependent biological self-assembly process, which can be defined as a more “biomimetic” approach. In particular, a number of case studies are investigated in more depth, more specifically those involving snail shells, clam shells, mussel shells, oyster shells, eggshells, and cuttlefish bones.

“…Waste water produced from the plants can cause environmental pollution, one of the most serious causes for the worst environmental problems is dye wastewater. 1 In addition, owing to the potentially cancer-causing properties and the toxicity of the dyes, wastewater from the dye produced in factories has seriously polluted the surrounding environment and threatened human health, even at low concentrations. 2 Among all kinds of water pollutants in wastewater, organic compounds are fatal to human health.…”

The harm and treatment of methyl blue (MB) were described, and the necessity for the removal of MB by magnetic nanomaterials was explained. Magnetic Ni-Mg-Co ferrites were prepared by the rapid combustion approach of an active nitrate solution and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR), energy dispersive spectroscopy, and vibrating sample magnetometer. Magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles prepared at 400 C with the saturation magnetization of 19.7 emu g À1 and the average diameter of about 15.2 nm were used to adsorb MB from the aqueous medium. The Brunauer-Emmett-Teller (BET) analysis showed that the specific surface area was 143.17 m 2 g À1 and the average pore size was 9.44 nm. The adsorption mechanism of MB onto magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was studied, and the results revealed that the adsorption properties conformed the pseudo-second-order kinetics model due to the square deviation values (R 2 > 0.98), and Temkin model could describe the adsorption state of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles, which suggested that the adsorption of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was monolayer-multilayer hybrid chemisorption mechanism. When the pH value exceeded 3, the adsorbance reached large value; while, the adsorbance was 97.6% of the initial adsorption value for seven cycles. The electrochemical impedance spectroscopy and cyclic voltammetry curves of MB adsorbed onto the nanoparticles before and after the adsorption were determined.
