“…After separation, the dark-brown precipitate was washed several times with methanol to remove the residuals. After washing, the final product was dried at 70 °C for 24 h. After preparation of treated PAC and PAC/γ ≈ Fe 2 O 3 nanocomposite, their characterizations were determined using SEM, XRD, and BET techniques [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , [16] .…”

Three types of adsorbents of powdered activated carbon (PAC), treated PAC, and PAC/γ ≈ Fe2O3 nanocomposite were used. The adsorption experiments were performed in batch conditions. pHZPC of PAC/γ ≈ Fe2O3 was 6.7. As a result, at lower than pHZPC, acidic pH, the adsorption of alizarin red S on PAC/γ ≈ Fe2O3 was favourable. The maximum of alizarin red S adsorption of PAC, treated PAC, and PAC/γ ≈ Fe2O3 was 24.5 mg/g, 57.8 mg/g, and 112.56 mg/g, respectively. The models of Langmuir and pseudo-first-order were a fit model to describe the adsorption isotherm and the Kinetic, respectively. The PAC/γ ≈ Fe2O3 is a promising class of the adsorbents in the adsorption of various dyes from textile effluents.

The variables examined were initial fluoride concentration, ZIF-8 and Uio-66 dosage, pH, and contact time. The residual concentration of fluoride was measured by a spectrophotometer. According to BET, the specific surface area of the ZIF-8 and Uio-66 was 1050 m2/g and 800 m2/g, respectively. Total pore volume and average pore diameter of the ZIF-8 and Uio-66 were 0.57 cm3/g, 0.45 cm3/g and 4.5 nm, 3.2 nm, respectively. The best pH for fluoride adsorption was neutral conditions. By increasing the ZIF-8 and Uio-66 dose, the fluoride uptake increased at first, but then decreased. Also, the maximum adsorption for ZIF-8 and Uio-66 was observed in adsorbent dose 0.2 and 0.6 g/L, respectively. The best model for describing kinetic and isotherms of fluoride adsorption were the pseudo-second-order model and Langmuir isotherm model, respectively. Based on the Langmuir model, the adsorption capacity of fluoride by ZIF-8 and Uio-66 was reported to be 25 mg/g and 20 mg/g, respectively.

The general goal of this data was to determine the concentration of fluoride and assess its risk in waters bottled in Iran. Seventy-one samples of different brands of bottled water were collected. Then, the fluoride concentration was measured through standard method for water and wastewater experiments. The non-carcinogenicity risk of fluoride for different groups of infants, children, teenagers, and adults was calculated by proper formula. The data presented here indicated that the mean concentration of fluoride in bottled waters was 0.272 mg/L, which is lower than the minimum world health organization (WHO) guideline. Further, the mean hazard quotient (HQ) values for fluoride across the groups of infants, children, teenagers, and adults with respective values of 0.0363, 0.2568, 0.1813, and 0.1452 were observed in 0, 1, 1, and 0 cases of HQ>1. Generally, in most of the tested brands, HQ value was less than 1, and this value was above 1 in only one brand of bottled water.
