In this study, derivative UV spectrophotometric methods were developed for the analysis of diflunisal, which is used as a nonsteroidal anti-inflammatory drug. Analysis wavelengths of diflunisal for the first and second order derivative UV spectrophotometric methods were obtained as 235.6 nm and 228.8 nm, respectively. The linearity ranges were found as 1.0-25.0 μg mL-1 for the first order and 1...

Abstract This study takes lead-zinc flotation tailings as the research object. The process of “tailings regrinding-lead-zinc mixed floatation-activation zinc separation” is used to comprehensively recover valuable metal elements from original tailings. results show that grinding fineness -74 μm under condition m accounts for 82%; recovery rates lead and in concentrate obtained open-circuit test...

This paper presents the study of bamboo as an alternative material for structure floating PV system. Bamboo is selected it used traditional house by Indonesian people. Additionally, a fast growing vegetation and can be found easily here. To investigate its potential, includes characteristics such physics mechanics, application subsequently component to analyse feasibility structure. In analysis...

Simple, accurate and precise spectroflourometric and spectrophotometric methods have been developed and validated for the determination of sitagliptin phosphate monohydrate (STG) and metformin HCL (MET). Zero order, first derivative, ratio derivative spectrophotometric methods and flourometric methods have been developed. The zero order spectrophotometric method was used for the determination o...
