The current study examines the feasibility of recycling artificially polluted wastewater that contains crystal violet (CV) organic dye by using Azadirachta indica sawdust (AISD) waste as a highly cost-effective adsorbent. Different analytical techniques, viz., SEM/EDX, TEM/SAED, BET, XRD, TGA-DTG, point zero charge (pHpzc), and FTIR, were used to characterize Studies batch adsorption performed ...

Tetracycline (TC) adsorption amount on original wood biochar was finitely, so modification is imperative to improve its capacity. This study mixed chinese fir sawdust with ammonium molybdate prepare a modified (MCB) via pyrolysis at 800 °C. Meanwhile, pristine (CB) produced as control. The effects of pH, time, initial concentration and adsorbent dosage the process were also studied. Langmuir mo...

Sawdust which is the main waste from wood industry has been used as a raw material forremoval of Brilliant Cresyl Blue toxic dye. The effects of various parameters such as pH,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg L-1. The optimum condition for the studiedparameters was applied for various con...

The adsorption ability of Dowex Optipore L493 resin modified with Aliquat 336 (MR), activated carbon modified with Aliquat 336 (MAC) and sawdust modified with Aliquat 336 (MS) for removal of Cr(VI) from aqueous solution in batch system was investigated. The effects of operational parameters such as adsorbent dosage, initial concentration of Cr(VI) ions, pH, temperature and contact time were stu...

Abstract Emerging contaminants are becoming a significant challenge for modern society. Antibiotic resistance is notably among the most urgent public health concerns, and it well recognised that problem often originates from wastewater treatment facilities. In developed countries, where affordable specified, activated carbon can be used as an efficient adsorbent of antibiotic residues present i...

The main objectives of the experiment were: 1) to compare bacterial populations of mastitis-causing organisms on the teats of lactating dairy cattle housed on sand and sawdust bedding and, 2) to examine the relationship between bacterial counts present in the 2 bedding types with those on teat ends. Sixteen lactating Holstein cows were housed on either sand or sawdust-bedded free stalls using a...

This report describes a green chemical method for controlling soil-borne plant diseases without disinfection using an equimolar copolymer of N-benzyl-4-vinylpyridinium chloride with styrene (PBVP-co-ST) that captures microbial cells alive on the surface and is highly biodegradable. Tomato bacterial wilt caused by Ralstonia solanacearum was controlled by the addition of sawdust coated with PBVP-...

To produce fruiting bodies of Oudemansiella mucida, porcelain fungus, on the oak sawdust medium, additives suitable for the mycelial growth and fruiting body formation were screened. In general, the mycelial growth of the three strains of O. mucida used in this study have been good on oak sawdust mixed rice bran of 20~30%. The mycelia incubated in potato dextrose broth for 7 days were inoculate...

To screen additives and their mixed ratio suitable for the mycelial growth and fruiting body formation of Oudemansiella radicata in the oak sawdust, additives such as rice bran, fermented soybean powder and wheat bran were used. Generally, the mycelial growth of O. radicata has been stable on oak sawdust mixed with rice bran of 5~20%. In case that O. radicata was cultured for about 30 days at 2...

Sawdust evaluation in bioremediation of PMS hydrocarbon polluted agricultural soil was carried out. The effect of different parameters; total petroleum hydrocarbon, dehydrogenase activity, optical density and pH on bioremediation performance were evaluated. Studied parameters such as microbial dynamics and hydrocarbon removal were found to be higher in sawdust amended system and differed signif...
