“…Other experimental conditions were an adsorbent dosage of 4 g/L and temperature varying from 25 to 55°C. This study's results reveal different conclusions from the study of Banerjee and Chattopadhyaya (). They affirm that, at beginning stages, the adsorption occurs rapidly and gradually slows down before reaching equilibrium.…”

This study investigates optimized tartrazine uptake by activated carbon prepared from biosolids (BBAC). Different tartrazine concentrations (10–20 mg/L), adsorbent dosages (1.0–2.0 g), pH (2.0–4.0), and contact times (60–120 min) were tested. These independent variables formed a 24 full factorial experiment arranged as central composite rotative design (CCRD). Response surface methodology (RSM) analyzed the responses of 50 experimental runs. Tartrazine removal efficiency fluctuated between 76.2% and 99.9%. The experimental data were best fitted by a quadratic model (R2 > 0.95, p > 0.0001). All variables exerted statistically significant (p < 0.05) effects on the tartrazine uptake (initial concentration, p = 0.0011; BBAC dosage, p = 0.0004; pH, p < 0.0001; contact time, p < 0.0001). Optimized tartrazine uptake efficiency of 97.4% can happen when variables mutually correlate at 10.1 mg/L of tartrazine concentration, 1.07 g of adsorbent dosage, 2.13 of pH, and 116.9 min of contact time. Practitioner points Production of biosolids‐based activated carbon (BBAC) is presented. Adsorptive affinity to tartrazine in aqueous solution was experimented. Experimental conditions optimized by Response Surface Methodology.

“…4) are often used to describe the sorption data. These mathematical models provide important parameters to characterize the sorption processes of dyes or metals binding by a wide range of sorbents derived from the plant waste biomass from the point of view of the sorption mechanism, characterization of sorption surface or affinity of sorbent to sorbate, and the practical utilization of studied sorbents as well (BANERJEE and CHATTOPADHYAYA, 2013;. For description of the obtained data, the linear and non-linear forms of these models can be used.…”

“…Dyes have a complex aromatic molecular structure and are generally resistant to light, temperature, and oxidizers. These characteristic features make the dyes non-degradable and therefore causes bioaccumulation in living organisms, leading to severe diseases and disorders (BANERJEE and CHATTOPADHYAYA, 2013). Dyes can affect aquatic plants because they reduce the sunlight transmission through the water as well as may impart toxicity to aquatic life and may be mutagenic, carcinogenic and may cause severe damage to human beings, such as dysfunction of the kidneys, reproductive system, liver, brain, and central nervous system (ADEGOKE and BELLO, 2015).…”

Agricultural wastes can be used as an alternative to the existing sorbents for the removal of metals or synthetic dyes from contaminated liquids. In this work, the fine powdered biomass of the hop (Humulus lupulus L.) variety Osvald's clone 72 and variety Bohemie as a sorbent for the removal of Cd from aqueous solutions of CdCl 2 spiked with radionuclide 109 Cd and synthetic dyes thioflavine T (ThT) or methylene blue (MB) from single dye solutions under conditions of batch systems was used. The maximum sorption capacity Q = 264 µmol Cd/g (d.w.) was found in the case of the leaf biomass of hop (H. lupulus L.) variety Osvald's clone 72 at the initial concentration of CdCl 2 10,000 µmol/dm 3 , whereby the sorption capacity decreased in the order Q leaves : Q stems : Q roots = 1.0 : 0.8 : 0.7. The sorbed amount of Cd was removed from the hop biomass with the following increasing desorption efficiency of the extraction reagents: deionised H 2 O << 0.1 mol/dm 3 HCl ≤ 0.1 mol/dm 3 EDTA-Na 2 . Similarly as in the case of Cd sorption, the kinetics of ThT and MB sorption by the leaf biomass of the hop (H. lupulus L.) variety Bohemie were also showed as two-phase processes. The maximum sorption of ThT approx. Q = 19 mg/g (d.w.) and MB approx. Q = 70 mg/g (d.w.) were found within the range of the initial values of pH 4 -7. The sorption of both dyes by the leaf biomass from single dye solutions decreased with increasing biomass concentration and on the other hand increased with increasing the initial concentrations of ThT or MB. The process of ThT and MB sorption was better described by the Langmuir model than the Freundlich model of sorption isotherm. From the obtained values of Q max , it was found that in the case of MB the dried leaf biomass showed more than 2-times higher sorption capacity (Q max = 184 mg/g; d.w.) in comparison with the value predicted for ThT. Obtained results suggest that dried plant biomass of hop (H. lupulus L.) as agricultural by-products can be used as a potential sorbent for both types of studied contaminants.
