“…Common methods used to separate heavy metals from industrial wastewaters include chemical precipitation, filtration, reverse osmosis, membranes, ion exchange and adsorption [5]. There are a variety of treatment processes deployed to remove heavy metal ions from the environment, but these, typically, are associated with expensive running costs [6]. Consequently, there is an urgent requirement to develop more-effective and low-cost processes to remove heavy metals from aqueous solutions [7].…”

Biosorption is an effective way of extracting heavy metal ions from aqueous solutions of various compositions. The brown algae, Cystoseria indica, when treated with sodium chloride, demonstrates significant capacity to extract cadmium and nickel, simultaneously, from aqueous solutions. The batch system was running over wide ranges of initial metal ion concentrations (5-150 mg/L), pH (2-6), adsorbent mass (1-4 g/L), and contact times (20-300 min), at a temperature of 25 °C. The results obtained when applying the system in these conditions exhibit higher removal capacities for cadmium than nickel. The optimal conditions of the biosorption process were found as the adsorbent mass of 1 g/L, initial concentration of adsorbates of 100 mg/L and pH of 6. The equilibrium data obtained are better described by the extended-Freundlich isotherm for nickel and cadmium. The maximum biosorption of nickel and cadmium in binary-metal-component system were 18.17 and 55.34 mg/g, respectively. The kinetic data derived from these experiments were evaluated with pseudo-first-order, pseudo-second-order and intra-particle-diffusion kinetic models. Kinetic examination of the equilibrium data derived from these models suggest that the adsorption of nickel and cadmium both follow the intra-particle-diffusion kinetic model.

In a pilot study, we observed cadmium (Cd) immobilization with citric acid (CA) and suggested that mandarin byproducts (MB), which contain CA at ca. 1.65%, can be used as soil amendments that reduce Cd bioavailability. In the present study, we (1) elucidated mechanisms of Cd immobilization by CA and (2) evaluated the use of MB as a soil amendment for Cd immobilization. In Experiment 1, CA was mixed with Cd contaminated soil at 0 and 3.5 mmol kg −1. We then added MB to Cd-spiked soil at 10, 20, and 40 g kg −1. Addition of CA decreased F2 (surface adsorbed Cd fraction) contents by 2.64 mg kg −1 compared with the control but was associated with increases in Cd fractions F1 (bioavailable Cd fraction) and F5 (residual Cd fraction) of 1.04 and 1.49 mg kg −1 , respectively. Addition of CA enhanced the concentration of fraction F5, likely reflecting Cd precipitation from soil solutions with increased HCO 3 − concentrations. However, although this treatment immobilized Cd, it also led to increasing residual and bioavailable Cd fractions. Unlike CA treatments, MB increased non-bioavailable Cd fractions without increasing the bioavailable Cd fraction. Moreover, at 40 g kg −1 , MB decreased F1 contents by 8% compared with the control, but increased F2, F3, and F5 contents by 3.6%, 0.7%, and 4.5%, respectively. Cd may be immobilized by MB through H x CO 3 − mediated precipitation as CdCO 3 following decomposition of CA and concomitant increases in the negative charge of soil due to the organic matter in MB. MB also improved the chemical properties of soils, with increased nutrient concentrations and cation exchange capacities.

“…In addition, 5 g of wet soil samples were centrifuged at 6000 rpm for 15 min to remove the pore water. The supernatant liquid was separated using a 0.45-μm membrane filter and was then measured for DOC concentration [29]. DOC was quantified with a total organic carbon (TOC) analyzer (Model TOC-VCPN; Shimadzu, Japan).…”

The nitrous oxide (N 2 O) emission of from arable soil following the application of manure is expected to vary by different animal manure types used. This study was conducted to determine the relationship between the type of animal manure used to amend soil and the amount of N 2 O emitted during the cultivation of sweet potato (Ipomoea batatas). An additional objective was to study the characteristics of nitrogen (N) and carbon (C) in different animal manures. Composted manures from chickens, cows, and pigs were applied to the soil at rates of 0, 10, and 20 Mg ha −1 , respectively. The availability and concentration of N and C varied by manure type. The concentration of NH 4 + was greater in pig manure (4638 mg kg −1 ) than in chicken (551 mg kg −1 ) and cow manure (147 mg kg −1 ). The mean cumulative N 2 O emission rate across soil application rates was also the highest with pig manure (11.9 kg ha −1 year −1 ), followed by chicken and cow manure, with emission rates of 10.8 and 10.1 kg ha −1 year −1 , respectively. The majority of N 2 O measured during the sweet-potato-growing season was produced from aerobic nitrification. Dissolved organic carbon (DOC) concentrations in animal manures did not affect cumulative N 2 O emission rates, and no significant relationship was observed throughout the growing season between the concentration of DOC in soil and daily N 2 O emission. Cumulative N 2 O emission rates depended on the type of animal manure and might be governed by NH 4 + concentration, rather than by total N concentration in animal manure type. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.
