Activated carbon prepared from Euphorbia tirucalli L wood (ETAC) by chemical activation with phosphoric acid has been analysed for the removal of Reactive Red and Reactive Blue dyes from aqueous solutions through batch adsorption technique. Lower solution pH favours the adsorption of reactive dyes. The amount of dye adsorbed per unit mass of adsorbent increases with the increase in temperature ...

In this research, the efficiency of electrocoagulation treatment process using iron and aluminum electrodes to treat synthetic wastewater containing Reactive Red 24 (RR 24) was studied. The effects of parameters such as current density, pH, type of electrolyte, initial dye concentration, electrolyte concentration, temperature, and inter electrode distance on dye removal efficiency were investig...

The present work was directed toward the successful ability of electerocoagulation to remove color from synthetic and simulated textile effluent by aluminum/iron electrodes. Two representative reactive dyes were selected for the synthetic dye system, a black dye alone and mixed dye (black, blue, red, 1:1:1 vol/vol). Several important operating parameters such as electrode material, initial pH(3...

The nitrogen-vacancy (NV) center is a defect in the structure of diamond, roughly the size of a single atom, that possesses properties that make it applicable to quantum information processing, high-resolution magnetic resonance imaging, and probing biological systems. When an NV center is excited by green light of wavelength 523 nm, it emits red light of in the range from 600-800 nm tens of na...

This set of notes explains the process that Prof. Jones used to develop the FSM for the lab. The lab simulates a vending machine mechanism for automatically identifying coins (dimes and quarters only), tracking the amount of money entered by the user, accepting or rejecting coins, and emitting a signal when a total of 35 cents has been accepted. In the lab, we will only drive a light with the “...

Batang ubi kayu merupakan limbah hasil pertanian yang memiliki kandungan selulosa sehingga berpotensi diolah menjadi arang aktif. Arang aktif dapat digunakan untuk menjerap zat warna salah satunya wara remazol red. Remazol Red satu banyak dipakai industri tekstil. Penelitian ini bertujuan mengetahui daya serap serta efisiensi dari proses adsorpsi dan menentukan tipe isoterm dengan menggunakan b...

Objective(s) Sickle cell disease is a genetic disorder characterized by chronic haemolytic anaemia. Haemoglobin S containing red blood cells may be susceptible to oxidative stress due to imbalance between production of reactive oxygen species and the countering effect of the various antioxidants present in the body. Materials and Methods We evaluated some antioxidant enzymes which include gl...

Currently, biological method has been utilized in the treatment of wastewater -containing synthetic dyes used by textile industries in Iraq. The present work was devoted to study the operating feasibility using reverse osmosis (RO) and nanofiltration (NF) membrane systems as an alternative treatment method of wastewater discharged from Iraqi textile mills. Acid red, reactive black and reactive ...
