“…Generally, increasing the initial dye concentration leads to decrease the percentage of dye removal which may be due to the saturation of adsorption sites on the adsorbent surface [9,30]. The amount of dye adsorption qt (mg/g) increases with increasing contact time at all initial dye concentrations as reported by various researchers [4,22,59].…”

“…If the adsorption capacity increases with increasing temperature then the adsorption is an endothermic process. The dye removal percentage of various dyes such as Congo red by modified hectorite [64], Congo red by organo-attapulgite [65] Congo red by raw pine cone and biomass based activated carbon respectively [27,30] were increased with the increase of solution temperature. However, the dye removal of Methylene blue by pine cone [4] and Methylene blue by montmorillonite clay [58] was reported to decreases with the increase of solution temperature therefore the adsorption process is an exothermic process.…”

“…However due to the high cost associated with its production and regenerat-4 ing, researchers are developing alternative cost effective and nonconventional potential adsorbents in the removal of dye from its aqueous solution. Various adsorbents such as commercial activated carbon [22], mineral [23], Clay [24], agricultural solid wastes [25][26][27] and agricultural solid waste based activated carbon [28][29][30] have been used in the removal of dyes from wastewater.…”

Dyes are complex organic compounds which are used by various industries to colour their products. These dyes are purged from various industrial sources such as textile, cosmetic, paper, leather, rubber and printing industries. Wastewater effluents contain dyes which may cause potential hazards to the environment. Some of these dyes are toxic, carcinogenic and can cause skin and eye irritation. Therefore, many researchers have been studied the effectiveness of dyes removal from aqueous solution by different separation methods. Different separation techniques have been used for the treatment of dye-bearing wastewater such as adsorption, coagulation/flocculation, advanced oxidation technologies, ozonation, and membrane-filtration, aerobic and anaerobic degradation. All dye separation techniques have their own limitation in terms of design, operation efficiency and total cost. This review paper provides extensive literature information about dyes, its classification and toxicity together with various treatment methods into dye adsorption characteristics of several non-conventional cost effective sustainable adsorbents. The mechanism and the effects of various physio-chemical process parameters on dye adsorption are presented here.

:In the present study, methylene blue (MB) dye was removed by Azadirachta indica which was prepared using raw Neem leaves through successive unit operation in a batch process. The effect of various operating parameters like inlet concentration of MB dye, adsorbent dose, pH of solution, and contact time were studied on percentage removal of MB dye. It was observed that the percentage removal increased on increasing the adsorbent dose, pH and contact time. However, it decreases on increasing the dye concentration. The maximum removal was found to be 93.11 % at 1 gmof NLP dose under 180 minute of contact time for 10 mg/l MB dye solution. Moreover, various isotherm models viz Langmuir, Freundlich and Temkin were fitted through regression on batch experimental data and it was found that Freundlich isotherm model best fits since the value of R 2 (0.996) is maximum as compare R 2 value of other models. Further, the unsteady state kinetic models were fitted on experimental data for understanding the phenomena of type of adsorption and it was observed that Pseudo second order model was in close agreement with experimental data .The theoretical equilibrium adsorption capacity was also found to be well validated with experimental equilibrium adsorption capacity. The maximum adsorption capacity of NLP adsorbent was found to be 5.7 mg adsorbate adsorb/gm of adsorbent. The SEM images of new brand prepared adsorbent and used adsorbent after 180 minute of contact time shows that the NLP is an effective adsorbent for MB dye removal.
