fertilizer plant waste carbon slurry has been investigated after some processing as an adsorbent for the removal of dyes and phenols using columns. the results show that the carbonaceous adsorbent prepared from carbon slurry being porous and having appreciable surface area (380 m2/g) can remove dyes both cationic (meldola blue, methylene blue, chrysoidine g, crystal violet) as well as anionic (...

Background & Aims of the Study: Methylene blue (MB) is a risk for human and environment. Adsorption process is one of the removal mechanisms of MB. The purpose of this research was the evaluation of low cost adsorbent of walnut bark granule for MB dye removal from aqueous environments. Materials & Methods: In this experimental research, the effect of various operating parameters...

to compare three various methods in the diagnosis of dentinal cracks formed in the apical third after root resection.one hundred extracted human maxillary central incisors were selected. the root canals were prepared with step-back technique. then 3mm from the apical end of all roots was cut perpendicular to the long axis of the tooth. the apical end of each root was evaluated to make sure ther...

introduction methylene blue was first described for the treatment of methemoglobinemia but practical usage of the compound for surgical purpose is common. the aim of this report is to describe a case of hemolysis in neonatal period as a potential hazard of methylene blue toxicity without presence of g6pd deficiency. case presentation in october 2015, a 36-week ga female infant with 2.05 kg weig...

The removal of Methylene Blue dye from aqueous solution using a biowaste, dried Blue Green Algae was investigated in terms of variation of initial concentration of the dye solution, adsorbent dosage and pH. The optimum pH for the removal of dye by adsorption was found to be pH 7. The data obtained in this study fitted with Langmuir and Freundlich adsorption isotherms. The experimental data conf...

A variety of adsorbents are available naturallyrice husk, neem bark, clays etc. that can be used to remove dye from the discharged waste. In this study,the use of lowcost, locally available, eco-friendly and highly efficient adsorbent has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. The removal of the textile dye Methylene blue (MB...

The mechanism of Methylene Blue adsorption on acid activated carbon Vitex Negundo Stem (AAVNS) has been studied through batch experiments. Generally, dyes are organic compounds used as coloring products in chemical, textile, paper, printing, leather, plastics and various food industries. The need for the treatment of dye contaminated waste water passed out from the industry. In this study, Vite...

Background & Aims of the Study: Dyes are one of the most contaminants in textile industrial wastewater that they are often carcinogenic, mutagenic and non-degradable. Therefore, with regard to environmental aspects, their removal from effluents is very essential. The purpose of this study was the perception of adsorption process and promotion of an economic technology for color...

introduction: discharging of industrial colored wastewaters especially into aqueous environments can cause adverse effects on aquatic life due to their toxic natures. in this study, montmorillonite modified by hexadecyltrimethyl ammonium bromide (hdtma-mt) was used for the adsorption of methylene blue (mb). materials and methods: the influence of surfactant loading rate, contact time, ph, adsor...

Among a wide range of pollutants, organic pollutants have given rise to major environmental concerns. Various methods have been considered to mitigate the damage, including catalytic reduction to less hazardous compounds. Catalysts that benefit from high surface area and suitable surface sites for various steps of the catalytic reaction have shown outstanding results in performing such duties. ...
