“…In acidic medium, protonation of the amine functionalities occurs and the interaction between dye anions and positively charged groups of the resin is enhanced. Such observations were described in the case of the azo dye adsorption on polystyrene and polyacrylic anion exchangers [ 32 , 33 ], C.I. Acid Orange 10 on an anion exchange resin (crosslinked acrylic copolymer based on divinylbenzene, ethyl acrylate and acrylonitrile functionalized with triethylenetetramine) [ 34 ].…”

Intensive development of many industries, including textile, paper, plastic or food, generate huge amounts of wastewaters containing not only toxic dyes but also harmful auxiliaries such as salts, acid, bases, surfactants, oxidants, heavy metal ions. The search for effective pollutant adsorbents is a huge challenge for scientists. Synthesis of divinylbenzene copolymer with glycidyl methacrylate functionalized with triethylenetetramine (DVB-co-GMA-TETA) resin was performed and the obtained microspheres were evaluated as a potential adsorbent for acid dye removal from dyeing effluents. The sorption capacities were equal to 142.4 mg/g for C.I. Acid Green 16 (AG16), 172 mg/g for C.I. Acid Violet 1 (AV1) and 216.3 mg/g for C.I. Acid Red 18 (AR18). Non-linear fitting of the Freundlich isotherm to experimental data was confirmed rather than the Langmuir, Temkin and Dubinin-Radushkevich. The kinetic studies revealed that intraparticle diffusion is the rate-limiting step during dye adsorption. Auxiliaries such as Na2SO4 (5–25 g/L), CH3COOH (0.25–1.5 g/L) and anionic surfactant (0.1–0.5 g/L) present in the dyeing baths enhance the dye adsorption by the resin in most cases. Regeneration of DVB-co-GMA-TETA is possible using 1 M NaCl-50% v/v CH3OH.

“…For example, chlorine decolorization of lignin-rich effluents in the pulp and paper industry leads to the formation of colorless but toxic and carcinogenic chlorolignins (Bohacz & Korniłłowicz-Kowalska, 2020;Wołowicz & Wawrzkiewicz, 2021). The widely used precipitation of lignins from lignocellulosic raw materials in the sulfite and sulfate pulping process leaves organic and inorganic contaminants in the effluent (Naseer et al, 2019).…”

Lignin is a phenolic biopolymer and a complex recalcitrant compound found in the wastewater effluent of the pulp and paper industry. Wastewater generated by the pulp and paper industry is having lignin as a major part in the form of black liquor, which poses serious hazards for the ecosystem along with health risks. Biological methods including the use of micro-organisms to degrade lignin by the enzymatic battery of various bacteria and especially fungi proved out to be effective. The present study includes the application of indigenously isolated fungal strains 81 from the effluent wastewater of a local pulp and paper industry of Pakistan. The strain was grown on lignin amended minimal salt media for the screening of best lignin degrader for determining their capability of lignin degradation and color reduction. Absorbance for lignin degradation and color reduction was measured at 280nm and 465nm respectively on the spectrophotometer. The results proclaim fungal strain 81 identified as Aspergillus fumigatus, after molecular characterization (accession no. MW132910 in NCBI data base) possess the potential to degrade lignin. Hence, it could help in the removal of lignin from toxic industrial wastewater.

“…However, the raw materials to produce activated carbon are expensive. According to Wołowicz and Wawrzkiewicz (2021), it costs around 1.5 USD/ kg to produce commercially used activated carbon from wood and coal. Therefore, alternate raw materials for activated carbon that are cheap but still able to render an effective adsorbent are highly sought.…”

Bamboo is one of the fastest-growing plants that exist on earth and can be found in many countries. Its application generally ranges across both the engineering and non-engineering sectors. Traditionally, bamboo is mainly used in the construction field, but recent trends and studies have also shown its potential in the water treatment industry as a low-cost adsorbent. Thus, this paper aims to highlight the recent studies on bamboo residue as a potential precursor for activated carbon as well as its performance in treating water pollutants. Apart from that, the current limitations, and suggestions on the further development of bamboo activated carbon, are also integrated to provide insight on its potential usage in the industrial process.
