Two novel adsorbents Holarrhena antidysenterica (HA) and Citrullus colocynthis (CC) were collected from native Pakistan and treated with tartaric acid.
The adsorbents were characterized by Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscopy, and their adsorptive behavior was studied against model cationic dye crystal violet (CV).
Role of biosorbent dose, time of contact, temperature studies, agitation rates, and solution pH was investigated.
Optimum conditions obtained for the removal of CV dye for H.
antidysenterica-tartaric acid modified (HA-TA) were as follows: 0.8 g adsorbent dose, 35 minutes contact time, 5.0 pH, 40°C temperature, and 150 rpm agitation rates as compared to H.
antidysenterica that gave 1.4 g adsorbent dose, 40 minutes time of contact, 6.0 pH, 50°C temperature, and 150 rpm agitation speed.
C.
colocynthis-tartaric acid modified (CC-TA) removed CV dye at 0.6 g adsorbent dose, 30 minutes contact interval, 4.0 pH, 40°C temperature, and 125 rpm agitation speed in contrast to C.
colocynthis which gave 0.8 g adsorbent dose, 40 minutes time of contact, 6.0 pH, 50°C temperature, and 125 rpm agitation speed, respectively.
Isothermal studies for both raw and modified biosorbents were compliant with the Langmuir model indicating monolayer, chemisorption.
The maximum Langmuir capacities were up to 128.20 mg/g, 136.98 mg/g, 144.92 mg/g, and 166.66 mg/g for HA, CC, HA-TA, and CC-TA.
Pseudo-second-order kinetic model well fitted the dye removal data.
The rate-determining steps involved both surface and intraparticle diffusion mechanisms.
Adsorption of dye molecules on active surfaces was governed by electrostatic attractions and chelating abilities.
Thermodynamics research revealed the spontaneous and exothermic nature of the reaction.
The adsorbents serve promising candidates for the effective removal of hazardous dyes from aqueous solutions.
