Several theoretical and empirical models are available to correlate experimental breakthrough curves of water pollutants, one of which is the two-parameter Belter model. Although not as well known as the century-old Bohart-Adams model, the Belter model is being used with sufficient frequency to merit wider awareness of its strengths and weaknesses. Through a systematic analysis, it is shown that the two adjustable parameters of the Belter model are analogous to the equilibrium capacity and rate parameters of the Bohart-Adams model. Breakthrough curves predicted by the Belter model are perfectly symmetric because their inflection points are invariant and always correspond to the midpoint of the curves. As a consequence, the Belter model provides poor fits to asymmetric breakthrough curves. In this work, an improved version of the Belter model is introduced. The new model with a floating inflection point manifests excellent conformity with mildly and, more importantly, severely asymmetric breakthrough curves.

“…was 95.55 mg/L, while dye toxicity to water eas, the 48-h LC50 was 18.26 mg/L. For the removal of RR141 dye from an aqueous solution, an alternatively low-cost adsorbent (corn stover with 3-aminopropyltrietoxysilane, CS-APTES) was developed and employed for capacitive adsorption (Carijo et al, 2019), as well as pyrrhotite ash (Mouldar et al, 2020), nanochitin particles (Boonurapeepinyo et al, 2011), and photodegradation by CdS nanomaterials (Senasu & Nanan, 2017). Various reactive textile dyes can also be decolorized by the bacteria isolated from the soil sample collected from contaminated sites, i.e., Pseudomonas sp.…”

An assessment of the phytotoxicity and genotoxicity of reactive red (RR) 141 dye was conducted using mung bean seedlings (Vigna radiata (L.) Wilczek). The dye exhibited phytotoxic effects, causing delayed germination and growth inhibition in pot plants. Plant parameters such as percentage of germination and seedling vigor index (SVI) were significantly reduced in mung beans treated with the dye at concentrations of 50 and 100 ml/L compared to the control group. Pot plant experiments were conducted with short-term (14 days) and long-term (60 days) exposures in paddy soil pot culture. In the short-term exposure, both plumule and radical lengths were significantly and dose-dependently decreased. In the long-term exposure, the dye affected plant length and grain weight, but had no impact on pod number, pod length, and seed number. To evaluate genotoxicity, high annealing temperature-random amplified polymorphic DNA (HAT-RAPD) analysis was used to detect DNA damage. Five RAPD primers with 58–75% GC content were utilized, resulting in the detection of polymorphic band patterns. A total of 116 bands were generated, with molecular sizes ranging from 433 to 2857 bp in the plant leaves exposed to the dye. Polymorphisms were observed as the disappearance and/or appearance of DNA bands in both concentration treatments compared to the control, and decreased genomic template stability (GTS) values indicated changes in the HAT-RAPD profiles, indicating DNA damage and mutation. These findings demonstrate that mung beans exposed to RR 141 dye experience significant effects on genomic template stability (GTS) and exhibit phytotoxic and genotoxic responses. This study highlights the potential of RR 141 dye as a harmful agent in plant model systems
