In order to conserve the energy used for remediation of harmful metals from aqueous media, an adsorption process was performed. It is efficient and low-cost method with zero carbon emissions as compared to other methods. A hematite-based novel nanomaterial loaded onto biochar was utilized for the remediation of toxic cadmium metal ions from aqueous media. Saccharum munja has been employed as low-cost feedstock to prepare the biochar. Three adsorbents i.e., raw Saccharum munja (SM), Saccharum munja biochar (SMBC) and hematite-loaded Saccharum munja bichar (HLSMBC) were used in batch adsorption tests to study uptake of metal ions by optimizing the experimental parameters. Experimental data and calculated results revealed maximum sorption efficiency of Cd(II) removal was given by HLSMBC (72 ppm) and SMBC (67.73 ppm) as compared with SM (48.7 ppm). Among adsorption isotherms applied on work best fit for Cd(II) adsorption on SM was found for a Freundlich isotherm with high values of correlation coefficient R2 ≥ 0.9 for all sorbents and constant 1/n values between 0–1. Equilibrium results were evaluated using five different types of errors functions. Thermodynamic studies suggested feasible, spontaneous and endothermic nature of adsorption process, while, the ∆H parameter < 80 kJ/mol indicated physiosorption and positive ∆S values promoted randomness of ions with increase in adsorption process. Data fitted into type I of pseudo second order kinetics having R2 ≥ 0.98 and rate constants K2 (0–1). Desorption process was also performed for storage, conservation and reuse of sorbent and sorbate materials.

Herbal industry of developing countries is facing several technical issues related to the extraction conditions in order to attain the maximum yield of a plant extract with maximum therapeutic attributes. Therefore the present study was aimed to investigate the best technique for respective herbal products. The effect of three different extraction techniques: ultrasonic assisted extraction, microwave assisted and orbital shaker assisted extraction, by using three solvents (80% methanol, ethanol, and ethyl acetate) on the antioxidant potential of Caralluma tuberculata stem (non-conventional vegetable) extracts were investigated. Folin-Ciocalteu method was applied on tested samples in order to find the concentration of total phenols. Therefore, the optimized extract of high yield and maximum total phenolic content was selected for further analysis like total flavonoid contents, FRAP, DPPH and ABTS scavenging potential. Quantification of phenolic acids in the extracts was also carried out by HPLC. Significant variation was observed in the yield of total phenols within the extracts, but better results were obtained in aqueous methanolic extract of ultrasonic assisted extraction, followed by microwave assisted and orbital shaker assisted extraction. Present findings supported the view that ultrasonic assisted extraction can be used for phytochemicals profiling, activity guided assays and the development of herbal products. Correlation coefficients of active principles indicated a significant relationship to antioxidant capacity P < 0.05.

Reports about presence and toxicity of Cd2+ in different chemical industrial effluents prompted the researchers to explore some economical, rapid, sensitive, and accurate methods for its determination and removal from aqueous systems. In continuation of series of investigations, adsorption of Cd2+ onto the stem of Saccharum arundinaceum is proposed in the present work. Optimization of parameters affecting sorption potential of Cd2+ including pH, contact time, temperature, sorbent dose, and concentration of sorbate was carried out to determine best suited conditions for maximum removal of sorbate. To understand the nature of sorption process, linear and nonlinear forms of five sorption isotherms including Freundlich and Langmuir models were employed. Feasibility and viability of sorption process were evaluated by calculating kinetics and thermodynamics of the process, while error analysis suggested best fitted sorption model on sorption data. Thermodynamic studies demonstrated exothermic nature of reaction, while kinetic studies suggested pseudo-second order of reaction.
