The test for benzoic acid was independent of the presence of benzene, aniline, diethyl ether, benzenesulfonic acid and phenol. Aryl chlorides, esters, amides and anhydrides interfere with the test.doi:10.1007/BF01220126Shahid Abbas AbbasiSpringer-VerlagMicrochimica Acta...
The “Environmental Hazard Profile” test scheme is described and relative bioaccumulation and biodegradation rates of approximately 100 chemicals belonging to various classes are given. Additional accumulation and degradation rates are given for representative benzene, benzoic acid, and phenol derivatives, an...

The indicator dye: pH indicator such as phenol red (PR) or bromocresol purple (BCP) at 0.0001-0.001%, just enough to be visible to the naked eye. The BCP is yellow in Buffer A, it changes to blue in Step 2 when B and A are mixed, and remains blue in Step 3 when A and B are...
Canavaliaensiformis (Jack bean), maleimidobenzoic acid N-hydroxy-succinimide ester (MBS), phenol red were obtained from Sigma-Aldrich. Water was purified with a Milli-Q Synthesis A10 water purification system. All other chemicals were purchased from Bioshop Canada and used without further purification...
(in particular to raise the refractive index). This compound should have one or two or more aromatic groups, but is not otherwise limited, and can be exemplified by benzene, toluene, xylene, phenol, benzyl alcohol, benzoic acid, benzyl benzoate, methyl benzoate, ethyl benzoate, propyl benzoate...
Column centrifugation method: took 200 μL of plasma, added an equal volume of saturated phenol/chloroform/isoamyl alcohol (25:24:1) to extract once, then used chloroform to extract once. Added 3 times of DNA binding buffer (6M sodium iodide NaI) to the supernatant then transferred to a co...
