“…Good correlation coefficients were obtained for the pseudo-second-order kinetic model, which shows that dye uptake process follows the pseudo-second-order rate expression. Similar types of adsorption kinetics were observed for dye adsorption onto clinoptilolite [26] and modified zeolite [27].…”

The adsorptive removal efficiency of Basic Yellow Dye (Astrazon Yellow 7GLL) from aqueous solutions was studied using different types of modified zeolites in an agitated single‐stage batch experimental system. Zeolite samples consisted of mainly clinoptilolite, collected from Bigadic Region of Turkey. The optimum adsorbent amount was found as 0.5 g in the primary experiments. Then, the adsorption kinetics with a constant initial dye concentration of 50 mg/L, agitation speed of 250 rpm, and temperature of 25°C for a period of 180 min were investigated. Three kinetic models namely, pseudo‐first‐order, pseudo‐second‐order non‐linear kinetic models, and the intra‐particle diffusion were used to describe the kinetic data of adsorption process. Non‐linear fittings of the Langmuir and Freundlich adsorption isotherm models were applied to the experimental equilibrium data obtained with dye concentrations in the range of 12–550 mg/L. The adsorption capacities (Qo) of zeolite samples for basic dye were in the range of 17.8–21.2 mg/g. Different analytical methods were used to investigate the influence of the different treatments on the zeolite surface and understanding of the adsorptive removal of dye using natural and modified zeolites. It was concluded that the spectroscopic results agree with the results obtained by kinetic and adsorption experiments as the acidic pre‐treatment zeolite has the highest removal rate for dye molecules since the concentration of various active sites (oxygen species, free Al+, and Si+ sides, etc.) to increase on the surface. On the contrary, basic treatment causes the loading of the surfaces with hydroxyl groups and these interact with each other via H‐bond and causes increased removal rate. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S185–S195, 2019

“…The superior washing fastness properties of the colorant might be owing to the affinity of colouring component caused by hydrogen bonding and Vander Waals forces for the dyed sample. The light fastness of the dye was fairly good due to hydrogen bonding between the hydroxyl and carbonyl groups of naphthaquinone, hence shielding the chromophoric group from fading [44][45][46][47][48][49][50]. The fastness with respect to light washing and rubbing were satisfactory of dyed samples at optimized extraction conditions and the technique was ecofriendly and could be used to reduce pollution [51][52][53][54][55][56][57].…”

This study is intended to scrutinize the consequence of extraction conditions of Lawsonia Inermis (henna) leaves on the color strength values of dyed fabric. Extraction pH, M:L ratio, and time were optimized using central composite design (CCD) under response surface methodology (RSM). We investigated how the maximum colour strength values were obtained at pH 6.64 in about 78 minutes extraction with an M:L ratio of 1:44. ANOVA results showed that all the extraction parameters significantly affect the colour strength values of dyed samples. 99% variation in the response was indicated in the 2 nd-order regression equation for K/S. The fastness properties with respect to light, washing, and rubbing were quite satisfactory of dyed samples under optimized extraction conditions.

Expansive soils are very important natural geological materials used in the geotechnical applications in the worldwide. After compacting, they are used as hydraulic barriers in earth structures, such as core of earth fill dams, landfill liners, and etc. However, these soils have some defects from technical points of view. To remove the defects, one of the soil improvement methods is mixing of these soils with granular materials. In this study, pine tree sawdust was used as granular additive material to stabilize the expansive soils. The effects of pine saw dust on the volume compressibility of expansive soils were investigated by using experimental studies under laboratory conditions. The test results showed that the pine saw dust positively affected the geotechnical properties in term of volume compressibility manner. As a consequently, the geotechnical properties of the expansive soil when blended with pine tree sawdust indicates that the pine tree sawdust is a good modification material for this problematic soil.
