Global access to sanitary water is of utmost importance to human health. Presently, textile dye water pollution and cigarette pollution are both plaguing the environment. Herein, waste cigarette filters are converted into useful carbon-based adsorbent materials via a facile, microwave-assisted carbonization procedure. The cigarette filters are co-doped with phosphorus and nitrogen using ammonium polyphosphate to enhance their surface characteristics and adsorbent capability. The adsorbents are characterized physically to examine their surface area, elemental composition, and surface charge properties. Batch adsorption experiments were performed to determine the maximum adsorption capacity of the adsorbents. Additionally, the effects of various adsorption parameters— temperature, adsorbent dosage, pH, and time—on adsorption process were examined. The doped adsorbent showed a maximum adsorption capacity of 303.3 mg g− 1 respectively, which is three times that of the methylene blue adsorption capacity of commercially available activated carbon (~ 100 mg g− 1). Thus, the phosphorus and nitrogen co-doped carbonized waste cigarette filter adsorbent shows a profound potential as a sustainable solution to combat textile dye water pollution and cigarette filter pollution simultaneously, due to its low cost, simple preparation, and versatility in application.

“…Recently, agricultural wastes have received considerable attention due to their abundant surface functional groups, porous structures, additional inorganic minerals, and high surface area. Many researchers study the dyes’ adsorption on various agro-waste materials such as corn cobs [ 18 ], oil cake [ 19 ], rice husk [ 20 ], sugarcane bagasse [ 21 ], gram husk [ 22 ], sawdust [ 23 ], pine cone [ 24 ], tobacco residue [ 25 ], white sugar [ 26 ], Astragalus bisulcatus tree [ 27 ], tea residue [ 28 ], vinasse [ 29 ], groundnut shell [ 30 ], and so on. This class of activated carbons have a valuable potential for the wastewater dye removal.…”

The adsorption of dyes using 39 adsorbents (16 kinds of agro-wastes) were modeled using random forest (RF), decision tree (DT), and gradient boosting (GB) models based on 350 sets of adsorption experimental data. In addition, the correlation between variables and their importance was applied. After comprehensive feature selection analysis, five important variables were selected from nine variables. The RF with the highest accuracy (R2 = 0.9) was selected as the best model for prediction of adsorption capacity of agro-waste using the five selected variables. The results suggested that agro-waste characteristics (pore volume, surface area, agro-waste pH, and particle size) accounted for 50.7% contribution for adsorption efficiency. The pore volume and surface area are the most important influencing variables among the agro-waste characteristics, while the role of particle size was inconspicuous. The accurate ability of the developed models’ prediction could significantly reduce experimental screening efforts, such as predicting the dye removal efficiency of agro-waste activated carbon according to agro-waste characteristics. The relative importance of variables could provide a right direction for better treatments of dyes in the real wastewater.

“…Neste enfoque, o Delineamento Composto Central (DCC) é uma das abordagens mais importantes e frequentes dentre os planejamentos usando MSR (MOUSAVI et al, 2018;ARCHIN et al, 2019), sendo adequado tanto para o ajuste de superfícies quadráticas como para a otimização de processos (OTHMAN, et al, 2017;ABBASI et al, 2016;KOUSHA et al, 2015). Deste modo, o Delineamento Composto Central Rotacional (DCCR) foi selecionado para avaliar o biofilme produzido por Bacillus sp.…”
