Industrial wastes with hazardous dyes serve as a major source of water pollution, which is considered to have an enormous impact on public health. In this study, an eco-friendly adsorbent, the porous siliceous frustules extracted from the diatom species Halamphora cf. salinicola, grown under laboratory conditions, has been identified. The porous architecture and negative surface charge under a pH of 7, provided by the various functional groups via Si–O, N–H, and O–H on these surfaces, revealed by SEM, the N2 adsorption/desorption isotherm, Zeta-potential measurement, and ATR-FTIR, respectively, made the frustules an efficient mean of removal of the diazo and basic dyes from the aqueous solutions, 74.9%, 94.02%, and 99.81% against Congo Red (CR), Crystal Violet (CV), and Malachite Green (MG), respectively. The maximum adsorption capacities were calculated from isotherms, as follows: 13.04 mg g−1, 41.97 mg g−1, and 33.19 mg g−1 against CR, CV, and MG, respectively. Kinetic and isotherm models showed a higher correlation to Pore diffusion and Sips models for CR, and Pseudo-Second Order and Freundlich models for CV and MG. Therefore, the cleaned frustules of the thermal spring-originated diatom strain Halamphora cf. salinicola could be used as a novel adsorbent of a biological origin against anionic and basic dyes.

“…The CR adsorption process predominantly follows the Pore diffusion model -modified Intra particle diffusion model, which shows that the rate-controlling step in CR adsorption onto the SZCZM1454 H. cf. salinicola frustules is mostly through the diffusion of dye molecules onto pores inside the adsorbent particles [126].…”

“…The paper, leather industries, textile and other pigment industries are widely applied CR dye for the processing of many products [10,11]. Also, the small quantity of the CR dye in aqueous system causes several serious cause lot of the human health issues including eyes irritation, diarrhea, and dysfunction of headache, convulsions, behavioral disorders, kidneys, liver, tissues, central nervous system gastrointestinal and other dangerous human disease [12][13][14]. Therefore, it is very important to develop a cost effective method for the removal of CR dye pollutant from the aqueous system.…”

“…Nevertheless, adsorption has demonstrated some success in the removal of dyes from aqueous solutions, and it is a technically feasible process as well [12,13]. Numerous studies have investigated the removal of dyes from aqueous solutions using a variety of biochars derived from agricultural by-products [13][14][15][16][17][18]. Biochar is an ideal adsorbent that can be developed from biomass through low-pyrolysis processes to adsorb dyes easily, sustainably, and in an environmentally friendly way [18].…”

This study investigates the adsorption of Congo red (CR) dye from wastewater using banana peel biochar (BPBC) in both batch and fixed-bed column modes. BPBC was characterized using FTIR, SEM, XRD, TGA, and BET analysis, revealing a predominantly mesoporous structure with a surface area of 9.65 m2/g. Batch adsorption experiments evaluated the effectiveness of BPBC in removing CR, investigating the influence of the BPBC dosage, initial CR concentration, and solution pH. Results showed optimal CR removal at pH levels below 4, suggesting a favorable electrostatic interaction between the adsorbent and the dye. Furthermore, a pseudo-first-order kinetic model best described the adsorption process. The Freundlich isotherm provided a better fit compared to the Langmuir and Dubinin–Radushkevich (D-R) models, implying a heterogeneous adsorption surface. The calculated maximum adsorption capacity (Qm) from the Langmuir model was 35.46 mg/g. To assess continuous operation, breakthrough curves were obtained in fixed-bed column experiments with varying bed heights (1–3.6 cm). The results demonstrated efficient CR removal by BPBC, highlighting its potential for wastewater treatment. Finally, this study explored the feasibility of BPBC regeneration and reuse through four adsorption–desorption cycles.
