Combined theoretical and experimental study of the photophysics of asulam.
J. Phys. Chem. A 117(10) , 2125-37, (2013) The photophysics of the neutral molecular form of the herbicide asulam has been described in a joint experimental and theoretical, at the CASPT2 level, study. The unique π → π* aromatic electronic transition (f, ca. 0.5) shows a weak red-shift as the polarity... |

Soil photolysis of herbicides in a moisture- and temperature-controlled environment.
J. Agric. Food Chem. 51(15) , 4331-7, (2003) The problem of maintaining the moisture content of samples throughout the course of a soil photolysis study is addressed. The photolytic degradations of asulam, triclopyr, acifluorfen, and atrazine were independently compared in air-dried soils and in moist (... |

Fluorescence determination of the pesticide asulam by flow injection analysis.
Anal. Sci. 22(1) , 21-4, (2006) This paper presents the analytical determination of the pesticide Asulam based on its native fluorescence. The method was optimized in either a flow injection analysis (FIA) assembly or in batch. The maximum fluorescence intensity was observed for basic pH so... |

Automated determination of asulam by enhanced chemiluminescence using luminol/peroxidase system.
Luminescence 24(6) , 448-52, (2009) A flow injection system with chemiluminescence detection for the determination of asulam, enhancer of the system luminol-H(2)O(2)-horseradish peroxidase, is proposed. The method shows a moderate selectivity against other pesticides usually present in formulat... |

An h.p.l.c. method for the quantitative determination of asulam, acetylasulam and sulphanilamide in peaches.
Food Addit. Contam. 1(1) , 67-71, (1984) An analytical method has been developed for the determination of the herbicide, asulam [methyl(4-aminobenzenesulphonyl)carbamate] and two metabolites, sulphanilamide and acetylasulam individually, in peaches. Asulam and acetylasulam were partitioned from an a... |

[The toxicity of herbicide Asulam].
Hua Xi Yi Ke Da Xue Xue Bao 23(2) , 190-3, (1992) We conducted a series of toxicity tests and short-term mutagenic assays of Asulam and 40% (W/V) sodium Asulam. It was found that the LD50 of Asulam with acute oral toxicity was 30000 mg/kg for mice, and the LD50 of sodium Asulam for mice and rats were equal (... |

Iron (III) aquacomplexes as effective photocatalysts for the degradation of pesticides in homogeneous aqueous solutions.
Sci. Total Environ. 298(1-3) , 219-28, (2002) The degradation of the herbicide asulam (4-amino-benzosulfonyl-methylcarbamate) was studied by excitation of iron (III) aquacomplexes in aqueous solutions at 365 nm as well as by exposition to solar light. Sulfanilamide was also studied as a model molecule. T... |

Pesticide adsorption by granular activated carbon adsorbers. 1. Effect of natural organic matter preloading on removal rates and model simplification.
Environ. Sci. Technol. 36(15) , 3426-31, (2002) The adsorptive removal of periodic spikes of the trace synthetic organic chemicals (SOCs) simazine and asulam from water containing natural organic matter (NOM) was studied in pilot-scale granular activated carbon (GAC) adsorbers over a period of nearly 3 yea... |

Pesticide adsorption by granular activated carbon adsorbers. 2. Effects of pesticide and natural organic matter characteristics on pesticide breakthrough curves.
Environ. Sci. Technol. 36(15) , 3432-8, (2002) The principal objective of this study was to elucidate mechanisms by which NOM affects the adsorption of a nonpolar (simazine) and a polar (asulam) herbicide on activated carbon. Experiments were carried out in microcolumns that were continuously fed solution... |
