Study on the Removal of Cadmium in Rice Using Microbial

May 11, · The optimum fermentation process, in which the rate of cadmium removal from the rice is 80.84%, required an inoculant amount of 0.1%, a liquid ratio of 1:1, a period of 60 h at 37 °C, and subsequently washed with water 4 times. The physicochemical properties of raw cadmium‐contaminated rice and fermented rice were studied.

Cadmium Removal from Aqueous Systems Using Opuntia

The best removal of cadmium (53.3%, corresponding to of 0.155 mg g −1) was obtained at pH 4.0 by using the TN sorbent. Infrared and Raman spectra confirmed that cadmium removal occurred via adsorption to –OH functional groups. 1. Introduction. Heavy metals receive world attention due to their long-term effects in the environment.

Removal of cadmium from wastewaters with low-cost

2/1/  · Probably, the removal of cadmium ions was attributed to a certain extent to formation of insoluble metal hydroxide species. In general, the adsorption of Cd (II) increased with the increase of pH. At low pH value, the protonation of amino and hydroxyl groups on the surface lead to low uptake of metal ions.

Stripping Cadmium plating and choosing a method

Dec 02, · I would not recommend blasting to remove cadmium, it will have two undesirable effects, potential for dimensional change and the fact you will contaminate your blasting cabinet with cadmium, so you will have to discard the blast media as hazardous waste and clean the cabinet. I would recommend using ammonium nitrate solution, 10-30%.

Removal of cadmium by Lactobacillus kefir as a protective

The aim of this work was to evaluate the capacity of Lactobacillus kefir strains to remove cadmium cations and protect eukaryotic cells from cadmium toxicity. Lb. kefir CIDCA 8348 and JCM 5818 were grown in a 1/2 dilution of MRS broth supplemented with Cd(NO 3) 2 ranging 0 to 1 mM. Growth kinetics were followed during 76 h at 30 °C by

Removal of Cadmium and Zinc from Aqueous Solutions Using Red

Red mud, an aluminum industry waste, has been converted into an inexpensive and efficient adsorbent. The product obtained has been characterized and utilized in batch and column operations for the removal of cadmium and zinc from aqueous solutions over a wide range of initial metal ion concentrations (1.78 × 10-5 to 1.78 × 10-3 M for Cd2+ and 3.06 × 10-5 to 3.06 × 10-3 M for Zn2+; contact

Cadmium Removal from Aqueous Solutions by Strain of

In the present study, the complete removal of Cadmium Cd (II) by Pantoea agglomerans from water by an electrochemical process has been investigated. According to the results from this study, we can affirm that the strain Pantoea agglomerans UCP1320 is an efficient biosorbent for Cd (II) in concentrations ranging from 1 to 100 ppm.

Individual and competitive removal of heavy metals using

The removal performance and mechanisms of three ions, cadmium (Cd(2+)), lead (Pb(2+)) and chromium (Cr(3+)) were investigated individually and as a mixture under different applied voltages and ion concentrations. It was found that CDI could effectively remove these metals, and the performance was positively correlated with the applied voltage.

Removal of cadmium from waters by adsorption using

It provides an effective method of cadmium removal to avoid cadmium health impacts described herein. The influence of different parameters on the effectiveness and efficiency of cadmium adsorption onto nanochitosan are presented by studying the effects of pH, initial cadmium concentration and the dosage of nanochitosan.
