This study was aimed to determine combustion characteristics and decay resistance of Spruce [Picea orientalis (L.)], Fir (Abies nordmanniana), Alder [Alnus glutinosa (L.)], and Iroko (Milicia excelsa) woods impregnated with ammonium tetrafluoro borate (1 to 3%) and the mixture of cement and borax (6% to 9%). The combustion test method was performed in three stages: flame stage, without flame st...

B-Zn-Si-Al compounds are modified Si-Al compounds made of sodium silicate, zinc sulfate, borax, and aluminum sulfate. They act as a fire retardant during the preparation of ultra-low density fiberboards (ULDFs). An orthogonal experiment was used to optimize the contents of the four compounds according to the limiting oxygen index. Fourier transform infrared spectroscopy was employed to prelimin...

Pesticides, formol, borax, and unpermitted colorants using in food production chain still need to control Vietnam. Our study aimed determine the chemical contamination some common samples collected at facilities, business stores, wholesale supply markets Lac Thuy district. As results, borax detected ratio of 15.9%, which "Cha" accounted for highest rate 25%, " gio lon...

Chemicals such as formalin and borax are actually chemicals that can only be used for purposes outside the body, meaning not allowed to enter human body because they will seriously damage organs inside. The purpose of this study was determine presence formaldehyde in snacks at SMAN 1 Nguter, Sukoharjo. This research method is experimental then summarizes entire research. turmeric dragon fruit e...

Wet noodles are a type of noodle with fairly high water content (35-52%), so it is easy to spoil if stored for more than 12 hours at room temperature. Misuse the addition borax and formalin by irresponsible food manufacturers, aims make wet last longer. This study determine whether sold in several traditional markets Sidoarjo contain harmful ingredients formaldehyde. The research design this be...

The actual function that it used non-food industry a cleaning agent, wood preservative, soldering antiseptic cockroach control. This study aims to identify content meatballs sold Gorontalo City find relationship between knowledge attitudes t...

The aim of the study was to develop an alternative capillary zone electrophoresis (CZE) for simultaneous determination of phillyrin (1), phillygenin (2), epipinoresinol-4-O-β-glucoside (3), pinoresinol-4-O-β-glucoside (4), lariciresinol (5), pinoresinol (6), isolariciresinol (7) and vladinol D (8) in Forsythia suspensa. The structural types of lignans 1-8 could be attributed to bisepoxylignans ...

Apigenin is a naturally occurring plant flavone that exhibits strong antioxidant, anti-inflammatory, and antitumor properties. A MEKC-UV based method was developed for the determination of total apigenin in selected herbs. Application of pseudostationary phase in the form of SDS micelles resulted in great repeatability of retention times and peak areas. A buffer solution consisting of 30 mmol/L...
