Sodium Tetraborate, also known as Borax, is a chemical compound which derivative of metal boron gas (B), used an antifungal compound, wood preservative, and antiseptic in cosmetics. The use Borax preservative food has been banned by the government. purpose this study was to help remove levels borax found meatball bulbs. Sampling determined Balongbendo District, Sidoarjo Regency. Analysis conten...

Borax or sodium biborate is a white crystalline compound that stable at room temperature. Ii usually used to make detergents and antiseptics. However, nowadays there still lot of borax added food ingredients chewier, such as tofu, wet noodles, meatballs, ​​chicken, fresh salted fish. Purple potatoe (Ipomoea batatas Var. Ayumurasaki) has fairly high anthocyanin content, 5.92-402 mg/25 mg purple ...

A facile route towards multifunctional hydrogels was proposed via borax catalyzed thiol-acrylate and borax–diol chemistry. The exhibited self-healable ability anti-fatigue property by merging dynamic boronate ester bonds micellization in one system.

TEMPO-mediated oxidation has been reported to effectively convert C6 primary hydroxyl groups to carboxyl groups for better water-solubility. However, the pH decreases continuously during the oxidation process, and it is therefore difficult to maintain the stability of the reaction. The control of pH at a constant level throughout the oxidation process is a complicated task. The applicability of...

Some chemicals used by human such as food additives are mutagenic and mutagenicity effects analysis of them is very important because of considerable consumption by man. One of the most common methods used in the recognition of the chemicals' mutagenicity is Salmonella Typhimurium Reverse Mutation (Ames) test. The purpose of the present study is mutagenicity effects analysis of sodium nitrite, ...

Daily dietary-boron intake and on-the-job inspired boron were compared with blood- and urine-boron concentrations in workers engaged in packaging and shipping borax. Fourteen workers handling borax at jobs of low, medium, and high dust exposures were sampled throughout full shifts for 5 consecutive days each. Airborne borax concentrations ranged from means of 3.3 mg/m3 to 18 mg/m3, measured gra...

Some pulp mills expect to produce viscose fiber by means of pre-existing pulp production lines as used for conventional kraft pulp having a relatively high content of hemicellulose. In the present study oxygenreinforced alkali extraction was used to dissolve the oxidized lignin, which increased the content of alpha cellulose and increased the degree of mercerization. This paper considers the in...

It is good to be reminded of drugs that not so long ago passed away in disgrace, for someone may have failed to bury a drug or may have mistakenly resurrected it, having forgotten its dangers. Not so many years ago I missed a diagnosis of Pink disease (but was put right by my friend John Black): a chemist had found a large packet of mercurycontaining teething powders. In the 1940s and 1950s the...

Flotation of soluble salt minerals such as potash, trona and borax exhibits similarities because all are conducted in their brine solutions. The most commercially important boron minerals in the world are borax (Na2B4O7.10H2O), colemanite (Ca2B6O11.5H2O), ulexite (NaCaB5O9.8H2O), and kernite (Na2B4O7.4H2O). Most of them contain low grades when mined and must be upgraded by mineral processing te...
