Factors affect on bioremediation of Co(II) and Pb(II) ontoLonicera japonicaflowers powder

Abstract

A B S T R A C TBioremediation is a low-cost eco-friendly separation technique for the treatment of pollutants such as heavy metals and organics from wastewaters. In the present study, a biosorbent, Lonicera japonica flowers powder (LJFP) was prepared from Lonicera japonica flowers (LJF) for treating Pb (II) and Co(II) from aqueous solutions and was well characterized by FT-IR and SEM-EDX. The kinetic results showed that the kinetics of both metal ions was rate limiting pseudo-second order. However, Pb(II) was also involved in chemisorptions, which was proved by the Elovich kinetic model. The equilibrium data of Pb(II) were tuned with Langmuir isotherm whereas Co (II) was fit to Freundlich isotherm model. The maximum uptake capacities of LJFP for Pb(II) and Co(II) were 19.61 and 43.48 mg/g at 298 ± 2 K, pH 6.0. Thermodynamic studies were conducted in the range of temperature, 298-313 ± 2 K, and were revealed that the sorption process of Pb(II) and Co(II) on LJFP was endothermic. Overall studies demonstrated that the biomass, LJFP is a promising, efficient, economical, and reusable sorbent.

Equilibrium and Kinetic Studies of Biosorptive Removal of 2,4,6-Trichlorophenol from Aqueous Solutions Using Untreated Agro-Waste Pine Cone Biomass

“…Owing to fast removal rates and high biosorption capacity, PCP can be used for cost-effective treatment of TCP from aqueous streams.Processes 2019, 7, 757 2 of 17 to develop cost-effective treatment strategy for the contaminated waste-water prior to release into the environment.The elimination of organic contaminants from the waste-water effluents using various methods like physical (membrane filtration, adsorption, biosorption and solvent extraction), chemical-biological oxidation, electrochemical oxidation, photocatalytic degradation, microbial degradation, ion exchange resins, catalytic oxidation, advanced oxidation processes have been proposed in the recent literature [9][10][11][12]. Among these techniques, the biosorption using various agricultural wastes has been thoroughly investigated for the elimination of organic contaminants and heavy metals from the standpoint of cost-effectiveness and eco-friendly considerations [13][14][15][16][17]. Several studies proved biosorption is a simple yet effective method for the elimination of pollutants, in which the significant factor is the utilization of agricultural wastes.…”

“…It also causes kidney damage and high blood pressure in adults and can lead to miscarriage, low birth weight, stillbirth and premature birth in pregnant women [7][8][9][10]. Ingestion of lead contaminated water has been implicated as a major route of lead toxicity [8][9][10].…”

“…Young children are more vulnerable to lead exposure because it affects the development of brain and nervous system [7,9]. It also causes kidney damage and high blood pressure in adults and can lead to miscarriage, low birth weight, stillbirth and premature birth in pregnant women [7][8][9][10].…”
