Biochar is becoming a low-cost substitute of activated carbon for the removal of multiple contaminants. In this study, five biochar samples derived from pine sawdust were produced at different pyrolysis temperatures (300 °C-700 °C) and used adsorbents to remove p-nitrophenol from water. Results indicate that, as the pyrolysis temperature increases, the surface structure of biochar grows in complexity, biochar's aromaticity and number of functional group decrease, and this material's polarity increases. Biochar's physiochemical characteristics and dosage, as well as solution's pH and environmental temperature significantly influence the p-nitrophenol adsorption behavior of biochar. p-nitrophenol adsorption onto biochar proved to be an endothermic and spontaneous process; furthermore, a greater energy exchange was observed to take place when biochar samples prepared at high temperatures were utilized. the adsorption mechanism includes physical adsorption and chemisorption, whereas its rate is mainly affected by intra-particle diffusion. Notably, in biochar samples prepared at low temperature, adsorption is mainly driven by electrostatic interactions, whereas, in their high-temperature counterparts, p-nitrophenol adsorption is driven also by hydrogen bonding and π-π interactions involving functional groups on the biochar surface.

“…hours and before activating, the samples were made sure to be in a semidried condition. Then, the samples underwent the activation process at 500 °C for four hours in muffle furnace to remove the non-carbonaceous components [21]. Lastly, the samples was washed with deionized water and 1.0 M of sodium hydroxide (NaOH) using vacuum filtration until the pH of the sample is neutral [22].…”

In this study, thedye treatment which is methylene blue ascertained with the activated carbon that prepared from the tamarind seed (Tamarindusindica). The conditions used to prepare activated carbon, using phosphoric acid as an activating agent at temperature 500 conditions may be attributed to enhance the surface area and pores development of TSC.Single point BET surface area (S and FESEM analysis showed that the pores development and formation were mostly in circle and oval pattern. The best conditions for TSC sample to adsorb MB effectively were at 50 mL of MB with concentration 120 ppm at temperature, 323 K by u maximum adsorption capacity for MB dye solution was 102.77 mg g In this study, thedye treatment which is methylene blue (MB) as water pollutants the activated carbon that prepared from the tamarind seed ).

“…Industrial wastewater pollutant separation chemical engineering procedures include adsorption. Adsorption experiments using different adsorbents are described in depth in column/continuous adsorption studies, whereas batch adsorption studies give crucial information and parameters for removing dyes [63,75].

Direct discharge of industrial effluents without treatment into natural sources poses a significant risk to the environment. Dye compounds are toxic and difficult for nature to process, causing serious physiologic harm to all organisms that come into contact with them. Water quality is directly impacted by the presence of methyl violet (MV) dye pigments as it reduces the photosynthetic activity of the streams, so it is crucial to eliminate it. Adsorption is generally accepted as a reliable method for getting rid of dye in wastewater. In most cases, the adsorption process is aided by the mutually beneficial interactions between the adsorbent, the dye, and the adsorption environment. This review highlights current scenarios of MV removal by various low-cost, eco-friendly adsorbents, and their efficiency. The removal of MV is examined in depth in this review paper, which discusses a variety of batch and column adsorption design experiments. Several parameters influence the adsorption process, which is the foundation of all laboratories looking for the best conditions. The primary goal of this review is to provide current information on the most researched affecting factors for batch and column operating modes. Flow rate, dye concentration, and bed height are all parameters in column adsorption investigations and contact time, pH, temperature, particle size, agitation speed, and adsorbent dose were all compiled for batch adsorption investigations and summarized in this review.
