“…These include adsorption, oxidationreduction, ion-exchange, precipitation, etc. Among these techniques, adsorption is frequently applied because of different adsorbents, such as active carbon (Lata et al 2008), kaolinite and montmorillonite ( Bhattacharyya and Gupta 2007;Ikhsan et al 1999), zeolite (Qiu and Zheng 2009), and boron waste (Olgun and Atar 2011;Yola et al 2014a, b). Besides, precipitation or oxidation-reduction technologies are preferred to treat pollutants with high concentrations because of its high efficiency, easy process, and cost-effectiveness as well as availability of different inorganic reagents.…”

Electrolytic manganese solid waste (EMSW) is a by-product of electrolytic manganese production and generally contains a high concentration of soluble Mn(II) (2000-3000 mg/L). Millions of tons of EMSW are stored in China, and the environmental pollution caused by manganese in this waste product is concerning. Unfortunately, little attention has been paid to the immobilization of manganese from industrial solid waste because manganese is absent from toxicological identification standards, and there is a lack of relevant quality standards in China. The objectives of this study were to immobilize soluble Mn(II) using chemical reagents, to analyze the immobilization mechanism, and to identify the most economical reagents. We investigated the immobilization degrees of soluble Mn(II) achieved by the reagents quicklime (CaO), carbonates (NaHCO 3 and Na 2 CO 3 ), phosphates (Na 3 PO 4 , Na 2 HPO 4 , NH 4 H 2 PO 4 , and Ca 10 (PO 4 ) 6 (OH) 2 ), and caustic magnesia (MgO) both individually and in combination. Our results showed that the use of 9 % CaO+ 5 % NaHCO 3 , 9 % CaO+ 5 % Na 3 PO 4 , 10 % MgO alone, or with 1-5 % NaHCO 3 or 1-5 % Na 2 CO 3 can reduce the amount of Mn(II) leached to 100 mg/kg when the eluate pH was in the range of 6-9. The most economical reagent treatments were determined using K-means cluster analysis. Analysis of the immobilization mechanism showed that CaO + NaHCO 3 may be favorable for immobilizing soluble Mn(II) as precipitation and oxidation products because the addition of NaHCO 3 releases OH − and buffers the system.

“…A specific uptake of metal ions by B. papyrifera leaf powder was enhanced from 0.94±0.07 to 43.40±1.83, 0.76±0.02 to 43.90±1.3, and 0.94±0.04 to 30.65±0.9 mg g −1 for Cu (II), Pb (II), and Cd (II), respectively (figure not shown). Higher initial metal concentrations are known to provide a favorable driving force in overcoming mass transfer resistance of metal ions between the aqueous and solid phases and thereby increase the specific uptake of metal ions (Lata et al 2008). …”

Paper mulberry (Broussonetia papyrifera) leaf powder was used to remove heavy metal ions from aqueous solutions. The specific uptakes of Cu (II), Pb (II), and Cd (II) by the leaf powder were 43.40±0.2, 43.9±0.5, and 30.65±0.9 mg g −1 , respectively, when 500 mg L −1 of the metal solutions were used. The data fitted well to the Langmuir isotherm. The process followed the pseudo-second-order kinetic equation and intraparticle diffusion played an important role in the adsorption process. On the basis of the calculated thermodynamic parameters such as standard enthalpy (ΔH°), entropy (ΔS°) and free energy change (ΔG°), it was inferred that the sorption process was endothermic and spontaneous in nature. The surface properties of the leaf powder (revealed by scanning electron microscopic observations) were suitable for the metal adsorption process. Energy dispersive X-ray fluorescence analysis confirmed the sequestration of the metal ions by the leaf powder. Fourier transform infrared spectroscopy implicated that different functional groups on the leaf powder were involved in the metal adsorption process. The results obtained from this study implicated that the B. papyrifera leaf powder was a good choice as a metal adsorbent. This abundantly available natural and ecofriendly biosorbent could be effectively used to develop a technology in the future.

“…It was concluded in the study that sulphuric acid treated carbonized Parthenium could be effective, low cost and easily available adsorbent for the removal of Ni (II) from dilute aqueous solution 94 . A study shows that dried powder of P. hysterophorus as an adsorbent for the removal of Cd from aqueous solution.…”

Parthenium hysterophorus (Linn.) is violent every where annual, herbivorous weed, commonly found in America but presently invaded in four continents. It shows hazardous effect on human health, livestock as well as it reduces the crop production due to its allelopathic effect. Partheniun with other constituents discussed are the cause behind the intimidating role of this weed. Inspite of these drawbacks the weed is traditionally known for the treatment of wounds, fever, ulcerated sores and malaria. It can also be used to increase the agricultural productivity and for the elimination of heavy metals from soil as well as from water to reduce pollution. The main aim of this review article is to summarise the main positive and negative effects of the Parthenium hysterophorus.
