“…According to this equation, the curve of qt versus t 1/2 should be linier, and then the intra-particle diffusion is the rate controlling step. However, if the line is not passing through the origin, it is indicative of the degree of boundary layer control, and the intra-particle diffusion is not the only rate limiting step [22].…”

Indonesia is one of the largest banana producing countries in the world remaining abundance solid waste of banana fruit bunch. The banana fruit bunch contains high natural fibers which were obtained by an impregnation process using potassium hydroxide (KOH) and followed by a carbonization process under steam at 250°C for 5 h. The nanomaterial of TiO2/fibre was prepared by a hydrothermal process at 200°C for 4 h. Surface morphology proved that the TiO2 was loaded into the fibre by an increasing roughness of the surface and irregular size of porosity. The development of amorphous to crystalline phase of TiO2/fibre was clearly observed. The effectiveness of TiO2/fibre for removal of rhodamine B was investigated from different parameters of adsorptions in aqueous solution. The equilibrium adsorptions show that the Langmuir and Freundlich isotherm exhibited the best correlation coefficient (R2 > 0.94) relating to the chemisorption and physisorption interaction in the adsorption process. Kinetic models were well described by the pseudo-first and second-order with the best correlation coefficient (R2 > 0.99). These results indicate that nanomaterial TiO2/fibre can be used as an effective adsorbent for removal of rhodamine B in aqueous solution.

“…Rhodamine B (Rh‐B) dye has its usage mainly in leather, printing, and industrial textile applications (Adegoke et al, 2019; Bello et al, 2020; Bello, Adegoke, Sarumi, et al, 2019; Bello, Lasisi, et al, 2017; Gad & El‐Sayed, 2009; Hii et al, 2009; Kadirvelu et al, 2005; Panneerselvam et al, 2012; Shakir et al, 2010). Rh‐B dyes cause redness and pain in the skin and eyes; it is carcinogenic and may also cause irritation (Inyinbor et al, 2016).…”

“…When perceived, Rh‐B dye causes respiratory tract irritations with signs of chest pain, cough, sore throat, and difficulty breathing. When consumed, Rh‐B irritate the gastro‐intestinal tracts (Anirudhan & Ramachandran, 2015; Attia et al, 2003; Dahri et al, 2016; Gad & El‐Sayed, 2009; Hema & Arivoli, 2009; Lata et al, 2008; Lim et al, 2017; Panneerselvam et al, 2012; Shah et al, 2013). Therefore, adequate treatment of these effluents for color removal becomes necessary before discharge into the environment (Jawad et al, 2016).…”

The use of acid‐modified mango pod (AMMP) sorbent for removing Rhodamine B (Rh‐B) dye from aqueous media was investigated. Raw mango pod (RMP) and AMMP sorbents were characterized using scanning electron microscopy (SEM), energy dispersive X‐ray (EDX), powdered X‐ray diffractogram (PXRD), Fourier transform infrared (FTIR), point of zero charge pH (pHpzc), and Boehm titration (BT) techniques. Batch adsorption was employed to examine the influence of operational factors. Sorption kinetic parameters were calculated using pseudo‐first‐order, pseudo‐second‐order, Elovich, and intraparticle diffusion models. The pseudo‐second‐order model best fitted the adsorption kinetic data most with maximum correlation coefficient (R2 > 0.99). The process of the adsorption was controlled by both boundary layer and intraparticle diffusion mechanisms. Four isotherm models (Langmuir, Freundlich, Dubinin–Radushkevich, and Temkin) were utilized to analyze the equilibrium data at various temperatures. Freundlich model gave the best fit with the maximum regression (0.99), while the Langmuir isotherm model established a maximum monolayer adsorption capacity of 500 mg g−1. Thermodynamic parameters studied revealed that the interaction is spontaneous and endothermic in nature. The cost analysis of the current study provides convincing proof that AMMP is efficient for removing Rh‐B dye from solution by providing a saving of 225.2 USD/kg, which is eight times cheaper than commercial activated carbon. Consequently, the study revealed that AMMP is a viable, effective, and sustainable sorbent for Rhodamine B dye removal. Practitioner points The powdered X‐ray diffractogram (PXRD) showed the formation of new and intense peaks with the presence of highly organized crystalline structures on acid‐modified mango pod (AMMP). Surface morphology of AMMP showed well‐developed open surface pores required for effective adsorption of Rh B dye molecules. Economic feasibility of the present study showed that AMMP is more affordable than commercial activated carbon that costs USD 259.5/kg, thus translated to a saving cost of USD 225.2/kg and more than 7.5 times cheaper than the commercial activated carbon (CAC).

: Organic dyes are used for dyeing cotton, plastic, wool etc. The dye manufacturing and dyeing industries are releasing unused organic dyes as an effluent. Every year five billion tons of waste organic dyes are pumped into river, ocean and other water bodies. The dyes are stable and non -bio degradable. Many methods are adopted to remove the dyes from dye effluent. But, these methods are creating another environmental issue and also dye removal is not 100% successful. Identification of Human, animal and fish poisoning organic dyes are essential, to control their toxicity. In this present investigation, sardine fish is selected to identify the fish poisoning and non -poisoning organic dyes through adsorption method. The experimental conditions like contact time, temperature, dye concentration, fish powder dosage are optimized to find out the maximum toxic effect of organic dyes on fish. The poisoning effect has been evaluated by adsorption thermodynamics, kinetics and isotherms.
