reactive dye acid dye water treatment flocculants
Biopolymer-based flocculants: a review of recent technologies.Flocculant is a kind of water treatment agent. It can aggregate the colloidal substances and particulate matters suspended in the liquid to form larger flocs, and then promote the settlement of these particles from the stable suspension (Salehizadeh et al. 2018 ).

Recent Advances in Hydrogels - ACS Publications
Methods for producing alginate hydrogels in macro- and nano-meter scales have been compiled in several reviews. 74 While these reviews are mainly focused on Ca 2+ 鈥揂lg synthesis, most of the reported techniques can be extended to other cross-linking ions by replacing the gelling bath solution (typically containing CaCl 2) for the one with the
Inquiry NowHydrogels: potential aid in tissue engineering鈥攁 review
Biodegradable nature of hydrogels has created much interest for drug delivery systems. The original three-dimensional structure disintegrates into nontoxic substances to ascertain an excellent biocompatibility of the gel. Chemical cross-linking is the highly resourceful method for the formation of hydrogels having an excellent mechanical strength.
