The N-bromination method (a PAM analytical technique based on N-bromination of amide groups and spectrophotometric determination of the formed starch−triiodide complex), which was originally developed for determining PAM in aqueous solutions, was modified to quantify substrate-borne PAM.

Using polyacrylamide (PAM) to reduce soil erosion in irrigated land has increased rapidly in recent years. A simple and reliable method to measure the PAM concentration in waters containing dissolved organic matter (DOM) is of great importance in assessing the fate and efficiency of PAM application. In this research, an analytical method to determine the PAM concentration of waters
Spectrophotometric determination of effective proteolytic
A new procedure for the determination of effective proteolytic activity in biodetergents has been developed. Effective enzyme activity is defined as the activity exhibited by the tested enzyme under real washing conditions, i.e., in the water suspensions of the biodetergent tested at the working temperature (usually 40°C).
Determination of protein concentration by spectrophotometer 1)Mix BioRad assay dye 1 to 5 (like 1 ml dye-5 ml mixture). 2) Standards are prepared. 1ml of mixture put in every tube. Proper amount of BSA standard added to each tube: (0, 2, 4, 6, 8, 10µg). Tubes mixed with vortex. 3) Samples prepared and mixed well

2.1.1.1. Nutrients . They were defined in 1996 by The Association of American Feed Control Officials “AAFCO”. The definition of AAFCO is “a feed constituent in a form and at a level that will help support the life of an animal [24, 35]”.There are many available nutrients, such as minerals, amino acids and fatty acids, but the most commonly used nutrients are vitamins and antioxidants

Introduction. All organisms contain proteases that hydrolyze peptide bonds in order to maintain systemic homeostasis and for its normal growth and development 1,2.Proteases derived from plants, animals and microbes find wide industrial applications including in the leather, food, brewery and pharmaceutical industry 2–4 corresponding to approximately 60% of the total worldwide enzyme sales 5.
- What is nonionic polyacrylamide?
- Nonionic polyacrylamides represent the smallest group of acrylamide-based polymers, representing about 25% of the total polyacrylamide market. Nonionic polyacrylamide is somewhat misleading since in the manufacture of acrylamide, regardless of the route, some degree of hydrolysis of acrylamide occurs.
- What is nonionic polyacrylamide (NPAM) gel?
- Nonionic polyacrylamide (NPAM) gel was prepared for in-depth profile control. A compact three dimensional network structure was formed in the bulk gel system. Retention, adsorption and bridging across the pore throats occur in high permeability zones. The NPAM gel shows superior high temperature resistant. °C.
- What is a polyacrylamide gel?
- The polyacrylamide gel is a polymer matrix of acrylamide cross-linked by N,N-methylene-bis-acrylamide (known as bis-acrylamide) as the result of a polymerization reaction between them, induced by tetramethylenediamine (known as TEMED) and carried out by ammonium persulfate (known as APS).
- What is nonionic powder flocculants / polyacrylamides (ndpam)?
- Nonionic powder flocculants can be produced with very high molecular weights, giving it the capability to form large, rapid-settling, good-compacting flocs. We produce nonionic powder flocculants / polyacrylamides (NDPAM) in a standard range plus in high and low molecular weights.
