This paper provides an overview of the purification effect of distillation process, along with the principles and research progress of different distillation techniques for small scale drinking water preparation. This paper also analyzes the advantages and disadvantages of each method, as well as ...
How does Ultrapure Water Help Chromatography? The improved sensitivity of widely used advanced chromatography techniques, such as LC-MS and High-Performance Liquid Chromatography (HPLC), demands water of the highest purity. That’s because a variety of contaminants, including dissolved gases, partic...
The improved sensitivity of widely used advanced chromatography techniques, such as LC-MS and High-PerformanceLiquid Chromatography(HPLC), demands water of the highest purity. That’s because a variety of contaminants, including dissolved gases, particles, colloids, bacteria and organic compounds, can ...
For water purification treatment various technologies are in use. There are two main approaches to water pollutions removal. First approach relies on the use of cheap adsorbents [2], [3] and second one employs photocatalysts like titanium dioxide. In 2001, Asahi et al. [4] prepared nitrogen ...
The above mentioned struc- tural similarity between the refolded protein and that obtained after purification suggests that the protein fraction that is unable to bind Pi corresponds to correctly folded protein. Most likely, during refolding this protein has acquired Pi, which is present as an ...
Characterization techniques Microscope analyses were carried out on an FEI Magellan 400L XHR SEM operating at 20 kV. Samples were centrifuged and dispersed in water previous to their deposition (10 μL) on an ultrathin formvar-coated 200-mesh copper grid (Ted-pella, Inc.). Average size and ...
Among filtration techniques, membrane disc filters allow to remove up to 80 % of treated MPs. In this case, particular attention must be paid to the choice of the diameter of the pores which if too large (mm) risk being ineffective for the MPs, while if too small (μm) they limit ...
By employing this method alongside newer or alternative techniques, it provides a reference or benchmark. This can help validate the results from other methods, ensuring accuracy and reliability. While the carbazole method has its drawbacks in terms of the time and effort required, its benefits in...
Among these, adsorption is one of the most promising techniques for the removal of antibiotics. It has the following advantages [11,12]: (1) simple process, (2) easy regulation of adsorbent properties, and (3) strong regeneration ability. In recent years, a large number of adsorbents includi...
Table 1 demonstrates the varying components of DF from different processing techniques. While the levels of moisture, ash, and starch in the DF remained relatively consistent, notable differences were observed in the protein content. The highest TDF yield was achieved through lactobacillus fermentation,...
