英文摘要:
The aim of the present study is to optimize the slow release biostimulant ball (BSB) for bioremediation of contaminated coastal sediment using response surface methodology (RSM). Metals contamination and stabilization of metals in coastal sediments using BSB were investigated. The effects of BSB size (1–5�cm), distance (1–10�cm), and time (1–4�months) on the stabilization of metals including Fe, Cd, Cu, and Pb were determined. The maximum stabilization percentages of Fe, Cd, Cu, and Pb, of 64.5%, 54.9%, 63.8%, and 47.6%, respectively, were observed at a 3�cm ball size, 5.5�cm distance, and a period of 4�months; these values are the optimum conditions for effective treatment of contaminated coastal sediment. The determination coefficient of the R2value suggests that >�91.55%, 89.97%, 96.10%, and 86.40% of the variance is attributable to the variables of Fe, Cd, Cu, and Pb, respectively. � 2016 Elsevier Ltd
